Take the vehicle to a nationally recognized parts store and have them check the alternator. I sounds like the voltage regulator is going bad and it is an integral part of the alt. If that checks out, have the body control module tested.

Most parts stores will do this for free, so there is no money out of pocket for you.

Let me know what you find.
