Man, it happened again! I was driving my 92 5.2 dodge ram today making and errand and it died...in the same damn intersection it dies at every time before. Sorry for bringing this up again, some of you will recall I had this same issue a year or so back. Seems like when it is cold I have this issue. I thought the problem was gone, but apparently that is not the case.But again I don't drive it much. Here is what happened. I got in the truck, it was probably 40 or 50 degrees out....sunny. Truck started right up. I waited a second or two then drove away from home. About 600 yards from my house, I turn on the main street and drive approximately a 1/4 to 1/2 mile. There is a slight curve in the road then I come up to the fear intersection. As I pull up to the red light, I put my foot on the brake to slow down. As I am almost at a stop I can hear the truck getting quiet then it starts to die. It dies. I crank the truck. It turns over easy, but does not start. I remember something the dealer had told me the last time this occurred. He said to push the gas pedal all the way to the floor. He said this stops new fuel from being delivered. I do this and crank the truck. A few seconds later it starts. I gas it once or twice to clear it out, then put it in drive. It dies instantly. Urrghh!. So I put my flashers on as people are honking. Im in the turn lane. Same exact spot(literally, within 10ft). I floor it and recrank. It starts. I put in drive... it dies. So I repeat. This time, I left it in park. It seems to run fine, in park. I rev the motor up, hoping it will warm up and help eliminate this issue. (Me and the dealer have always thought it was temp related)But after paying the dealer a $1000 for multiple diagnostic sessions I am not sure. I thought the last time they got it, but was still unsure, hence the reason I only really drive it when I need to pick up lumbar or it is warm out. Anyway, I let it warm a second or two in park, rev it up, and basically dump it into drive, it chirps a little bit, almost dies, but I gased it enough to get it driving. I drive about an 8th mile and park it. Go inside for 20mins, come back out. Starts right up, and I drive home. This really bugs me, and I can't believe I am the only one to have this issue. I want this fixed but I am tired of throwing money and parts at this problem. Please anyone knowledgable, can you please help or ask a buddy mechanic or someone. Seriously, if I could get this fixed, I would even consider shipping some beer off to someone. Feel free to ask me questions. I am mostly a "parts changer"...not a mechanic, but I can answer most things we have previously done to it before.

My 83 318(2bbl carter) acts the same way because I have no choke at the moment. When it's fully warmed up it's pretty much OK. I cant offer much help but there's been several occaisons that I just wanted to floor it & blow it up & then leave it sit & call a cab.

First thing that popped into my mind was it sounds like your conver lock up isn't disengaging and it's causing your truck to act like a manual when you dont push the clutch in.
I wonder if there is a way it disable the lock up like you can do W/ a GM trans?
Or you could just try putting it in neutral the next time it feels like it's going to die.
I never had this problem nor do I know if it's even possible. Just what came to mind as I read your post.
Good luck

If it dies only when put in gear it sounds like a torque converter issue.My old 93 dakota did this and when i pulled the trans the pan was full of metal from the converter disenegrating.

I'd really look hard at the fuel pump module. Sounds like the pump is dying.
Or the filter on the pump may be plugged, after it sits for awhile the dirt moves away and it runs again ,I'd drop the tank and check for dirt in the tank,and change the pump filter! I had a similar problem with my 95 Ram!

We previously gave the truck a tune up. New plugs, wires, cap, rotor, cleaned the throttle body, checked the wiring and connections. Looking for loose or non grounded items. Without using a wire testor hard to tell if there are any wire breaks under the wire wrap. We have changed the coolant temp sensor, ait temp sensor and Map sensor. No codes from the computer. I have thought about the intake and or head gaskets, because the dealer once said he noticed a puff of smoke during start up. I have not actually seen this, but why would he make it up. I also thought about valve seals. But again, why only when it is cold? During the summer months it drives great. I am trying to keep the truck around because it is paid for and otherwise, nice to have for hauling. I am just finishing up my garage project and am anxious to finally get back to working on my muscle cars which have been sitting for 10 years, so I don't want to spend all my free time or money on this truck. So I am stuck because the dealer can't seem to find it without breaking my bank and the issue seems complex and above my previous attempts. But someone has to know.

92 Ram used an SBEC controller. ECT is on a dual range scale. At cold start it has a 4.75 - 1.25 volt range. At approx 125 degrees F, the ECT volts should have dropped to 1.25v. At this voltage the SBEC internally adds a resistor and the ECT volts JUMP UP to approx. 3.75 and then again use the 5v scale downward as the engines continues to heat up. Verify that this transition is happening at approx 125 degrees then MOVE on............
Good luck
I have a 92 5.2 Dakota that had the same symptoms. Had to replace the black box on the fender under the hood. SBEC controller?? Anyway. after we replaced it I never had another problem

That cost you $1000.??? The intake gaskets or valve seals are not going to make it die on the road. You have to verify if its fuel or not. Go back and read my post again, that will determine if its fuel or not. Don't replace parts or drop the tank until you isolate the problem. It may be the computer although that year they were not bad for computers. Again, isolate the problem and go from there. I work on this stuff every day.

Do yourself a favor and actually test the fuel pressure with a guage. Knowing what the actual pressure reading is the correct way to diagnose the problem. To little pressure as well as to much fuel pressure will both cause a host of problems.
Also check your steel fuel line from the tank for rust. You may not see/smell anything, but a tiny pin-hole will defeat your pump. DAMHIK...

Is that a tbi? I had a 90 tbi equipped ramcharger with a bad sbec (computer) that would die when I hit a nasty bump, took a while to locate that prob. The bummer was, that the computer available at the dealer is only rebuilt and not available new. Still cured the prob. for me.
'92 should be the SMPI Magnum motor.
Definitely, check fuel pressure and for any codes.
