I'd recommend checking the batt voltage at the batt and with lights on, etc. I had the same sort of thing happen to our stock 2.0l several months ago and although voltage wasn't too bad there was not enough current producing ability with the alternator and the regulator, alternator and batt all died away, but slowly. It was worse on cold days and got better when the car warmed up or without much electrical load. I had to have the alt load tested and it showed weak. I know it is a pretty good expense but the rule of thumb I have used for forty years of cars is to replace all three when one goes as the others are close behind. Good luck.
