When I am driving, sometimes the door locks will lock/unlock on their own and the gauges will go haywire. When I stop and turn off the key, I lose all power to everything. Also, sometimes when I turn off the key the CD player will try to change CDs over and over, even when no CD is present. ---

You may want to start by checking the cable connections to the battery and the connection of the negative cable to the chassis to be certain that there isn’t a build-up of corrosion. If this doesn’t cure the problem, the next step I would take is to have the battery and charging system tested.
