Possible Voltage problem 2013 jetta hybrid
 

I’ve been experiencing a possible voltage drop however I don’t know what it’s from. I’ll be driving the car and I’ll loose the transmission completely. Then it just throws a check engine and epc light and won’t move until a couple hours later when it resets it’s self.I’ve also tested both the battery and alternator and they are good.
