You could be experiencing an PCM problem that is effecting the charging system that could be going over voltage then dropping to under voltage, if this is indeed the the case it is very hard on the cars electronics, unfortunely you are at the mechanics mercy on this as it can be very hard to locate your problem unless the computer did manage to store a trouble code, take it to a shop you trust, tell them what you have experienced, you don't have to go to the dealer, most good shops have the necessary equipment to work on your vehicle.
