Weird Issue - never seen/heard this problem before

[TB360]

While driving, all these lights came on. Oil and fuel are gone. Power remains the same though, no decrease or anything, no CEL. In addition to the errors on the dash, lost my XM/Aux connection, air-condition was not blowing cold air. Pulled over to the shoulder, turn off the engine and then no crank. To make it work and fire up the engine again, had to open the door and locked them, then unlock and boom, everything back to normal. After a few miles, all errors came back. When I got home after 30 miles, and let it cool for an hour or so, drove again for 10 minutes and back home, error free. I never heard nor read this issue anywhere. If it was the stabilitrack, why did the oil, fuel, my xm were affected? Seem like they are all connected somewhere? Like I said, everything is working fine now and back to normal except for my XM, does not recognize my iPhone for playing music but it charges it.

The only thing I have done prior to this was to have the fuel pump replaced but it was a week ago and it has been fine. Any thoughts?

Check:

The battery terminals, make sure both are firmly connected and that both termination points (especially the ground as mentioned) is connected properly.

The ground for the IPC. In the passenger footwell just below the side of the center stack under the lip of the carpet, there's a splice pack with a bunch of grounds hooked into one, this can sometimes mess with stuff up front.

If both of these two check out completely and thoroughly, I would begin suspecting the serial data bus.

. I was afraid it was something expensive and I received some great advice on what the issue could be. Fortunately it was just the ground wire right next the the positive terminal on the side wall. I have no more issues and actually have much brighter lights and more bumper in my system. Thanks again for all the info.

It is amazing what a lack of solid ground does to the systems in these trucks.

It was indeed the battery cables not being tight. Well, it was tight but not the correct tight. Drove 160 miles with no issues. Even on rough roads there was no problem. I got my xm/aux channel back too. Thank you to all of you...
