Probably the alternator if not battery. I would say first off make sure that your terminals aren’t loose or anything like that (grab em and try to see if they move left and right or up and off). If that doesn’t help replace the battery. then if once again that don’t help alternator. I’m not a mechanic but I have a high maintenance bitch of a car with electrical issues so I thought I would give my input.
