Could be a # of things. Starting w/fuel filter cannot waste much $ & may correct it. Have you checked with GM? They might agree to fix it under warranty?;) s

Analyze the computer with an OBDII scanner. Check for codes...

What is "a while"? Do you mean just sitting there idling? Driving? How long?

How's the idle? It starts but you didn't say whether it ran rough or not.

runs fine at idle, takes awhile before cars dies, drive an hour to work one day and it died when i got there, but drove home with no hassle unitl i arrived in my drive way. alernator went, replace with new one, changed spark plugs, before car started sputtering and dying change thermostat after thinking it was old never been replaced before.

may change fuel filter next and plug wires never been change either > check spark when it refuces to run.

Full sentences, punctuation better, easier to read.

Yep, could be a blocked catalytic converter element. Age of the car and the fact that all the other obvious stuff checks out. Try seeing how long it will maintain a med-high rev before stalling. If the cat is blocked, it could conk out after only five minutes or so.

If you've never changed the plug wires in ten years, that's going to be a problem no matter how you look at it. Those are cheap and easy to do, so I'd do that regardless of whether that's the actual problem.

Sputtering out after running sounds a lot like a catalytic converter though...
