So I've been chasing this around for a long time now. It's been going on for 6 years, but has recently gotten much worse. I'll be driving, and my gauges all drop and every warning chime goes off. Blinkers and lights still work on the outside, but nothing on the inside. The cluster back light is still on, but gauges not working. At first it would only happen in the extreme heat or cold, and only here and there(like every few months), which made me think there's Expansion and contraction, breaking a connection somewhere. Lately it has been happening almost every time I drive, and in any temperature. Most Recently even my head unit will shut off. If it is not reset by the time I get out of my truck the head unit will stay on and drain my battery. With all of the research, I see similar issues, but nothing the exact same. There seems to be a lot of ground issues With these trucks, and I've looked at everything I can find with no luck. My gut says it's a connection issue of some sort, whether ground or not. Any info greatly appreciated. I tried uploading a video of the issue, but it says the file it too large, even after cutting it down to a few seconds
