The vehicle is an '87 Dakota 3.9L Automatic with 83,000 original miles. On the way back from a 20 mile round trip, the truck starts misfiring, bucking, and diesiling while still running, then finally stalls. I crank it over and finally starts when I push the pedal to the floor. It runs but real crappy for 30 seconds and stalls again. I pop the hood, check wiring, carb, choke etc. and all looks good. No smell of excess fuel. I wait a few minutes and it starts right up and runs perfectly. I drive another 5 miles, let it idle, start and stop it a few times and it runs perfectly again. If it did it once, its bound to do it again far away from home. Any ideas? I'm thinking of swapping a spare computer into it. Any other ideas or known issues to look at first? Tough to diagnose while running perfectly.

IIRC some had a dist gear problem.Seems the gears would wear out.Cam gear was still good but the dist gear wore.Had a few at work years ago.The first one gave us fits.Then I talked to my friend at the dealer and he told me about the gear.Rocky

The dist pickup and crank pos sensor are both known to crap out when hot....But yours started when hot....probably not them.
