My 1997 Pontiac Grand Prix engine lights (oil, ABS, service soon) come on and the car shuts off. Restart and it does it again. Had TPS, Computer and TPS pigtail replaced. What next?

I would look at the ECU. Run OBD II on it and see what comes up. (Unless, as I think you said, you replaced it.) It sounds to me like sensors are running crazy. This may be a serious problem with the engine or with the sensors. If you cannot run the car for more than 10 seconds take it into a shop. If you do this stuff yourself there's no guarantee.

You might also check to see if there is a chip in your ignition key. I had the same symptoms when my chip went bad in a 2002 grand prix. The vehicle thought it was being stolen. Approximate replacement for mine was $80. Charlie Jeepspur@iwon.com

It seems to me that it may be a momentary power loss of some sort. I assume that there were tps codes stored. Were there any loss of comms codes stored? It really could be many things. What codes are stored?
