Have you checked the fuel pressure at the rail?

Its TBI, there is no rail, and it is kind of a pain to check fuel pressure.

Have you done the normal tune up stuff? I would check the fuel filter, and give it new plugs/wires/cap/rotor, and also check the timing.

i was thinkin fuel filter. id start with that if you dont know the last time its been replaced, its like a 8 dollar part... if thats not it, plugs n wires

okay new developement the plugs are missmatched between autrolites and bosch platinums....and the resistance on the wires is so out of wack that its causing the coil to over heat and thats what we are sure is causing the problme and i bought a fuel filter too for good measure

Maybe you have a bad catalytic converter. Does it die when the car gets warmed up?

CONFIRMED! IT WAS THE FUEL PUMP THE MOTOR WAS WEAK I WASNT GETTING EVEN ENOUGH FUEL PRESSURE oops...caplock lol anyways i replaced the pump and the harnes the old one was questionable and it runs way better and no dies in a 3 days and now you can hear it lol. oh and i also confirmed that the idea to cut a hole in the trunkc to get the module up will not work on our 4th gens the metal lines go all down the front and off the side i know you can with a 4th gen but i forgot about the metal lines on the thrid gen..... i cut the hole and everything.... but in the end i didnt have to drop the axle any just put it on stands amd the drop the exhaust and the head sheild and i jockied it out.... so it weasnt a total loss
