Try disconnecting the battery and leaving it that way for about 10 min. Reconnect and see if does anything. I have seen weird things with chrysler cars and misfires.

have it scanned for codes and freeze frame it by a pro he can check misfires if a sensor is screwed up . the only thing you can do now is check compression an d fuel pressure with a gauge. auto parts rent it.low fuel pressure as well as a vacuum leak can cause these as well as basic engine problems.
