If its been a while sense you have chg. fuel filter,DO IT, If still does the same after that, do fuel pressure test, fuel pump might be on its way out. $$$$$. If pump and filter chks. out ok, than maybe its fuel regulator. My best guess its either filter or pump.

It sounds like you may have a cloged fule filter, start with that and then check to see if your fuel pump had gone bad. Most likely it's your fuel filter if it's never been changed. The other common problems is a partial clog to the injectors but i don't think that is the problem here. Good luck

I have a 2K1 Tahoe that was doing the same thing. It wouldn't idle properly and would die at stop lights. The check engine light would come on once in a while for a few seconds. I took it to a dealer and they removed and cleaned the soot like residue and other build up from the throttle body. That fixed the problem and I haven't had any problems since then. Hope this helps.
