Had similar problems occur on various Chrysler products manufactured since 1986. What I did was remove the computer from the car and then take a Dremel tool with wire brush attachment and lightly buff all the pins of the computer--tops, sides and backs. After this I then take a jewelers round file and insert the tip into each connector pin hole and very lightly file it to remove any corrision. When I reassembling the connector plug to the computer I placed a good size dab of silicon grease on the plug in the center (acts as a seal when seated). This has eliminated the problem on four different vehicles.

Have a compression test done while the engine is warm,It sounds like you have a valve sticking open sometimes or maybe even a burnt valve.

one is the crank sensor,m the other is the cam sensor-which was it? you should get the actual code so there is no doubt, if you are having a hard time getting it started, it is probably a crank sensor, if it only manifests itself when running it could be either crank or cam sensor.
