I have seen more than one Dodge truck act that way because of a bad O2 sensor. The sensor "drops out" and the computer starts to correct the fuel mix using default values and the sensor come back and the PCM tries to adjust again.

This might be in left field but is the battery okay? Does the engine turn over?
