Have you tried a new battery? I had AutoZoo test the battery and Alt in my car, and they said all was good. I was having the same issues you were. Needless to say a week after the test, I was replacing the alternator, but the batterywas not holding a charge. Replaced the battery and all is fine now, electrically anyway.
