You could have a problem with your alternator, which supplies electricity to the engine. That is the most common problem I've had with my neon.

The other possibilities could be that the O2 sensors [pre and post the catalytic converter] could be damaged or dirty.

Heres a question that could help answer the question. How long does it stay started before it cuts off? if the answer is roughly 5 to 10 minutes at most, then its the alternator. If the answer is about 1 to 2 hours depending on if your driving on the highway then it could be the O2 sensors.
