5.3L -102,000 miles. Several problems, however I will start with the major problem of stalling while driving. First started noticing problem when I drove it to Phoenix (hot) a week ago. The vehicle will eventually start back up after a couple of minutes, runs fine for ten to twenty miles, then same thing. This is all in the day time of eighty five plus degrees, notice at night time it runs fine with out stalls. Is something overheating? The stall usually happens when you demand a little more acceleration, then idle speed drops below 1000 then turns off.
I took it into the dealer shop with no bad checks, all is well I am told, no SES light. Changed spark plugs, change air filter to K&N, fuel system clean process. Checked transmission fluids.
Other problems; Speedometer not working, Bose stereo system works when it wants to, Service air-bags light comes on at random.
Some say it is the fuel pump going bad, I had that replaced several months back. Would daytime heat play a roll in malfunctioning in the pump?
