yes any automotive shop has a very cheap test i forget what its called but it checks your starter--alternator----and battery.

costs like 20 bucks or so.

If it's not the battery or the alternator, check the grounds. I went through the same thing for about 3 years of new battery, then replaced alternator. Went thru dying batteries, car would die while rolling. Not good. This fixed it for me:

I've had the same issue that's surfaced after having an aftermarket headunit installed. Perhaps I need to take it to an audio shop to find the culprit.
