A fuel pressure test should be performed as I suspect the fuel pressure regulator is leaking fuel into the vacuum line causing the engine to flood on restart.
A drop in fuel pressure would confirm this.

Will not start without putting foot on gas
I had the same problem. You should clean out your throttle body. You can prob do it yourself in 20 minutes or less. My 04 grand prix starts up everytime now.

04 grand prix shuts off
My 04 Grand Prix was doing the same thing. Not sure if what I found was the reason for it, but I removed the air filter portion of the intake, reached into the intake a little pulling the throttle plate down. It was caked in carbon build up. With a lint free rag and some throttle body cleaner, I scrubbed the plate and since have not had anymore issues with the car not starting. Hope this helps anyone.
