It sounds like there is a broken wire or a bad connector on the coil. The wiring can deteriate inside the insulation. I think you basically found the problem, but now you need to take it to the last step. When the truck is running, wiggle one coil wire at a time to see which one is causing the problem. Something tells me you will replace a wire and it will be fine. Also, Chrysler had some splices that would corrode and loose connection, so check for that if you see any. Normally they are within the tape harnessing wiring.
Let me know what you find. This is an interesting one.
