We have a '95 Rodeo with a 3.2 liter engine that I can't figure the reason why it won't start.

The symptoms:
at first it would run for a while then it would just die as if the gas was cut off. We let it set for a few minutes then it started fine and we made it home. Next day, started right up, idled for maybe five minutes then just died. Started it up again, ran for a couple minutes then died, and now it won't start at all. The fuel pump is working--I can hear it back by the tank and I can hear fuel flowing up at the engine. The fuel pump relay seems to be working okay and I replaced the in-line fuel filter encase it was restricting flow. Even tried starter fluid sprayed into the air intake--no help.

Any help diagnosing the problem would be greatly appreciated.

I am Stumped!
