Question about 2003 GMC Yukon
While driving downtown in a large city my 2003 Yukon XL all of the sudden just stops running. I put it in park and turned the ignition it doesn't start, but try it again and it does. After attending my event I was on the way home and about 75 miles down the road it does it again. The engine just stops, I pull over and restart it and it runs fine. The check engine light has been on for awhile and we have taken it to our local mechanic and he hooks it up to his computer and there is an evap sensor that comes up but it doesn't come up with an error. He replaced the fuel filter and cleaned something in the engine and it ran well for about 3 weeks at which time it happened again. This time the engine stayed running, but when I tried to give it gas it wouldn't accelerate. I tried pumping the gas, putting into neutral and pumping the gas, so I pulled over to the side of the road and put it in park and tried pumping the gas and nothing. Turned it off, restarted it, the 2nd time it refired and I drove home. Took to our mechanic and he said he didn't know the cause, but reset the sensor. Any thoughts?
Get your fuel injectors cleaned. I had the same problem.

I had the same issue with another GM and never got it resolved except by replacing the battery.
Finally put it one that keeps good voltage while park or running.
Wall mart sells a $20 alternator and battery checking device you plug into a power socket.
Its digital read out is better for my eyes than the dash board one and has idiot color codes red yellow and green,
Some batteries seem to get shorted cells and that lower voltage can lead to engine shutdown even while driving. You would think a good alternator would keep the engine running but these new low rpm designs with heavy load...
This is all experience and I do not claim to be a GM tech.
