Don't worry i was on my property driving to recreate the issue, the only thing I could've hurt was myself by crashing into a tree.

Onto the issue, a few minutes after startup and driving the traction control, abs, and brake light all light up on the dash. When this happens I lose headlights, foglights, A/C, wipers, power windows, power locks, and turn signals/hazards. However my radio still works and I can get forward lights if i pull the brights towards me(they wont work if I push forward.) After anywhere from 30 seconds to 10 minutes it all kicks on as if nothing happened.

I've brought it to 3 Chevy dealerships they've changed tire sensors and brake sensors. I've had the fuse box replaced and ensured the grounding packs were on bare metal with no exposed wire.

It doesn't happen as often as it used to, but it still happens. Has anyone encountered something like this before? Or should I just throw the entire truck away and start over?

Thanks for reading my diatribe.

Were any of the Dealers able to duplicate the issue? Did any of the Dealers report finding active or history DTCs? What was the reason given for replacing the tire sensors, assuming that you mean the sensors mounted inside the tires. What do you mean by "brake sensors"? The wheel speed sensors?

Is the truck a daily driver? Has it spent any time parked outside without being driven?

Two dealers duplicated the issue and one was able to catch it before it shut off and said it was shooting so many codes they didn't know what was wrong.

I meant brake switch, not sensors. The reason they gave to me about the tire sensors was them saying that was the code they saw.

I bought this truck last February so I can't say how long it sat undriven previously, but it is my daily driver.

I would love to see the mess of codes it tosses before shut down.
Personally I think you have a poor connection in the can communication system.

If a lot of weird electrical issues start showing up after a vehicle has sat unused for a period of time it is usually a good idea to accomplish a thorough inspection of all wiring. Rodents of all sorts love to chew on insulation.
