I have a 2007 gmc Yukon and it keeps stop on me it say reduce engine power then I have to wait then minutes then I can pull off again
You should get the codes read, but I suspect the Throttle Positioning Sensor on the throttle body. Checking the codes anywhere from a p1515 to p1519 would show up. Replace the wiring harness plugin also. Usually there is a broken wire at the plugin. Sometimes the plugin comes with the TPS.
Took the vehicle to dealer. He put it on the machine and couldn’t find anything wrong.
