Replaced fuel filter and cleaned throttle body when stalling at low idle...fixed that issue...now the Tahoe is stalling at random (at highway speed) but it is picking back up on its own at times and then other times it has to be restarted. No Codes...88,000miles...Other forums have shown this issue but no one has answered. Can anyone help?

Note: A while back I thought the fuel pump was bad...took tank down...the plug to the pump had come loose...plugged it back in and no problems until now.

My bet is the fuel pump

You will have to pressure test the fuel system to rule out the fuel pump. Otherwise without codes you are waiting for a hard failure to point you in the right direction.

Thanks... The unfortunate side effects of COMPUTER Controlled systems( The BEST/WORST invention for shade tree mechanics).
