Having problems with your 2002 Pontiac Grand Prix ?

My 2002 grand prix with a 3.8 will start and then die. it will only do it after the engine is warm. when i start it the first time for the day it starts fine but after driving it for a bit then shutting it off it will do that. also noticed that it will fluctuate once i get it going. but eventually level out almost forgot after 3 or 4 tries or pressing genly on the gas and fluttering the pedal it will start. never seen this problem before. thanks
