While driving all my electric guages, door looks, and radio quickly flash on and off for 15-30 seconds. The compass in my rear view mirror goes crazy, my speedometer goes 0 to 150. I don't think I lose power steering, brakes, or engine, but hard to tell going 70mph on the interstate.

Have trouble codes checked. See if anything points in the right direction?

There are three things to check, the left fuse block, the trans connector, and wiring branch by parking brake may be chafing. The trans connector may have a few wires backing out and need fixing as well as left fuse block. Pics included.
