My 08 half ton is doing something weird right now

When I'm cruising and hit the blinker or break pedal it kills half the speakers then they come back. Or it kills the aftermarket radio (installed for a few years without issues) and then it reboots and comes back on with music playing

The other day it lit up the red air bag logo on the dash and made the temp and direction deal on the rear view mirror show some alien words :rof

And now while cruising (and not doing anything) the doors locks would cycle

I disconnected the battery and parked it last night so I will try driving it tonight and see what happens...

I mean, it can't cause my breaks to lock up..... Can it!?

I could handle it dying, but screeching to a stop would be nuts!!
