HI, I have a 98 GTP that did the same thing. I am a mechanic and I knew that the supercharged grand prixs had a lot of fuel pump resister problems. Well one very quick test that could solve your problem, disconect the fuel pump resistor and use a jumper wire to bypass the resistor, on the conputer side of the conector. Then start it, if it stays running u have a bad resistor.
