Lights flicker. Stabil track warning light. Door locks going crazy. Truck shutting down while driving. When i hit brake or flick high beam or turn signal. Any suggestions. My wife drives my truck with my two boys because its a 4 door. I cant have that happening on them. It unsafe.

    So, multiple electrical failures. First steps would be for you to check all battery connections and engine-to-frame ground connection. Clean and tighten as necessary. Also check serpentine belt tension.

    Then if that doesn't cure anything, you should have the battery load-tested and the alternator output checked.

    If those are ok, then I'd have the car scanned for trouble codes. There are a lot of possibilities here.
