You’re suppose to clean the area where the ground goes, that’s the main cause.Mine use to cut off at a red light or idling , my negative ground wire had oil on it, once I changed the mega fuse and cleaned all connections and that oiled wire , I ran it for 2hours it was fine.
Thanks fam! That last bolt made me think i was gonna have to take the bumper off.
You? Me too lol. And I was not trying to do that!
I’m looking at a 2007 Yukon now with a no start issue it doesn’t have any power going to the starter
I would check the starter relay/ fuse

A bad ground may be some people’s issue but my grounds were clean and fine. My issue was the starter.
