95GT Hesitation when hot start

[_taz_]

I have a 95 GT that seems to run great except for one problem that seems to be getting more annoying and dangerous. The car starts and runs fine, but if I stop at a store or something and run in for a few minutes, when I come back out the car starts fine, and will rev up normally, but if I let out the clutch the engine will nearly die, thers is no power. Depress the clutch and rev the engine and it's fine, but try go go and it just dies. Try to pull out into traffic and you become a hood ornament. after a few minutes it seems to be ok. It seems to be worse the hotter it is outside. It reminds me of vapor locking on carbs. Anyone got any ideas of what to check?

Thanks
