Possibly a clogged or constricted fuel line between the tank and the
pump or the pickup in the tank. Somewhere downstream of your pressure
gauge. While the car is sitting, the pump is able to build up
adequate pressure, but, once the engine is started, it can't push/pull
fuel through the system fast enough to keep up the pressure.

Assuming both filters are new, I'd ohm out the pump ground wire. >> Stay informed about: 99 grand prix gtp 3.8 wont stay running HELP |

While it doesn't happen very often be sure to checked for a blocked exhaust.
Just have someone at the exhaust when the car starts and make sure something
is coming out. Had a much older Ford with similar symptoms with a totally
blocked catalytic converter. >> Stay informed about: 99 grand prix gtp 3.8 wont stay running HELP |

I'm having the same problem!In testing if on the fuse relay panel you
jumper the f/pmp spd cont relay between pin 30 and 87a it should start and
stay running. still testing to find out why i need to do this. but this
counts out cat. conveter and fuel pump, as this is the fuel pump speed
controll relay (car speed ie. if in park or neut. can't over rev eng.)will
post findings any help out there? >> Stay informed about: 99 grand prix gtp 3.8 wont stay running HELP |

From looking at the diagram my guess is that your fuel pump resistor is open
circuited.
According to the service manual here is where it's located:
Mounted to the outside of the right front frame rail forward of the front
wheel

I searched the archives and found a listing on 2005-july-05 under 2000 GTP
runs 5 seconds then die tells you where the resistor is and how to fix.
pulled mine off it was bad did ohms test on it and keep getting random
values so siver surfer is right. Thanks everyone I will pick one up
