Hello, I'm new to this and need help. My 2011 durmax will turn off while driving or idling at random times. The stabilitrak and or the traction control will appear on dash . Took to the dealership and they said it's a 5amp wire that was grounding out causing truck to short and stutter. After being in a week they could not find anything and said it was probably fixed. They charged me nothing which I thought was weird.I drove home and it did it once again. Please help I completely lost on this. Has anyone had these issues before
