my father in-laws van will stop running during drive after about 15-20 minutes of 55mph. It will shak alittle just before it shuts down and we have to wait 25-30 minutes before it will start again now when it first shuts down and we check for spark it doesnt have spark but right before it does start we get spark. We thought mabe the fuel pump but it does kick on when started. We have replaced the coil pack, and fuel filter, and the cam sensor.
we are not sure what else could be causing this problem.
You may have intermittent pcm problem. The next time it stalls try tapping on the PCM and see if it starts.
I just had a 01 caravan in my shop last week with the same type of problem. Replaced the PCM with a
used one and it works fine now.
Also try tapping on PCM case with it just idling and if it
stumbles you'll know that its the culprit! PS use a small hammer, but don't get too carried away!
Hope this helps!
