2011 durmax

[Chevydiesel11]

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

This isn't really one of those things that can be remotely diagnosed. I guess the first place I would start looking though is under the under hood electrical center/fuse panel. I worked with a local Tech on a truck that was doing something similar. I don't recall if it was a no crank/start or a shut off/kill issue, but if memory serves he ended up replacing part of the electrical center.
