The coil could be the problem, you can check with an ohm meter. Also check the connector where the ignition switch plugs into the dash harness on the steering column.
I was having the exact same issue as you, and I found the pin burned on the red wire.
very good point/suggestion. Also check the firewall connectors making sure there plugged in right. 20 plus years ago I soldered the big red wire togeather under the steering coluum, end of that problem. I cut a zip tie off to get these pictures and pulled up some shrink wrap so you can make out the red wire. with a bigger peice of shrink wrap around it and I zip tie it to the coluum.

That checks out ok too. Just like new.

Ohm the pickup coil, should be between 300-550 ohms. Easy to do with no tools except the multimeter. You should check it hot and cold, it's easy to trouble shoot imo.
The pickup coil measures .295 at slightly above room temp.
Factory service manual says it should be between 350-550, all 4 that I have checked and ran have checked at 335 ohms and the cars runs well. I think your good at 295 ohms?

This is what I found:
I cut the connector out and used some male/female spade connectors and heat shrink to make it a good connection, and the problem went away.

My car did the same thing last year, and it was the ECU (MP orange box, installed in about '94 or '95). Also on the "suspect" list is the pickup coil.
Just to let everyone know who helped I got it fixed. I wound up replacing the orange electronic control box. I just put an orange one on about 4-5 years ago and didn't even drive it one year. Probably don't have 2000 miles on it. I replaced the ballast resistor, the coil, - (because it was the wrong ohms for the car and was leaking oil), the distributor pickup coil, (actually a whole other distributor) and checked the fusible link with all the wiring connections on the fire wall and the steering column too. I called the Mopar Performance tech line and spoke to an older gentleman and he said that the coil is suppose to read between the to terminals 0.75 - 0.81 ohms. Mine was 1.5 ohms. Although this will work it puts an extra load on either the ballast resistor or the ECU box can't remember which he said now. But, that's a very good possibility for the electrical problems and eating ballast resistors for lunch all the time. When you go to replace a coil see what the spec on the coil is and then go with that spec. Just wanted to let everyone know encase someone else may have this problem. I bought my box from Jegs because they are running Mopars now and I will support them now over Summit. Nothing against Summit, just want to help my fellow Mopar drivers.
Thanks to all. Jeff.

FWIW: I just had a similar experience with my car. It would just shut off...like turning off the ignition. Which it was.
You didn't mention (or I didn't read...) what ignition your running, but I had some corrosion build-up on the pick up & star wheel in my distributor that closed off the air gap. I cleaned the parts and all is fine. I'm running an MSD Pro Billet and from what I've read on their forum, this is an acknowledged problem. Don't rule it out with your set-up.

I'm running all stock ignition except for Mallory Coil and Mopar's orange electronic control box. I changed the whole distributor out eliminating anything in the distributor including the pick up coil and reluctor clearances inside.

Orange box is notorious for being junk. A stock box is better than the orange ones.
I recently had some "shutting off" issues which were fuel related not spark. But when I was chasing my tail looking for spark problems I tested every ECM which I had accumulated over the years. I have six of them and they all checked out good, as I drove each one for at least a day or even three before I put the next one in. I have been running a MP "chrome" one like for 10 years?
Anyway I think this last stock box that I tested is better than my "chrome" box. I tested the car out in Nevada at 4500 ft and it ran great at hi speeds for miles at a time in hot weather with this box/ECM. The car idles better with this box also. Pretty much a acid test. So I'm keeping this stock box in the car. My [image]http://[/image] 110 mph
