LS1 Camaro fuel issues Ok guys, here's the problem that I've been getting here lately. Not sure if anybody has seen this before or not, but it's got me puzzled a bit here.
I've got a 99 Camaro LS1 and after about a hour of highway driving, from work to home, the car at times will sputter a bit and sometimes will completely die out. It's definitely more prevalent when the temps are higher outside. Seems as if it's flooding itself and won't fire back up after it dies. Only way it seems to restart is by turning the key back one click so that there are no lights on the dash and waiting anywhere between 15-30 seconds. Previous owner of the car said he installed a new fuel pump from gmpp, but who knows if it was really done or not. Trap door method was not used and can't drop the tank right now as it's my daily driver.
Has anybody else seen this happen? I'm guessing maybe the venturi isn't correct, or fuel bucket might have holes in it? Or if there is a thermal protection switch in the fuel pump, it could possibly be tripping and not resetting until after I turn back the key and wait a few.
Any guesses or input on this one guys?

Anybody want to take a venture and toss something out here? Does it seem like I am barking up the wrong tree here? Should I be looking at something else like maf, iac, emissions components?

Thanks, just trying to get a starting point so that I can start and try diagnosing it and eliminating possible components. Thought first off could have been fuel delivery related. Going to get a fp gauge on it so that I can see what the fp does when it starts with the symptoms.
