No start high idle?

My jeep is doing this weird thing. the battery will act dead then it will come back to life? Now when my jeep starts it idles at 2500 rpm? I have no clue what is causing this. Is it my alternator? a sensor. I'm lost...

Batteries do not "come back to life". Have the battery Load Tested.

If you a high idle, you have a vacuum leak, a Throttle Position Sensor issue, or an Idle Air Controller issue. Clean/inspect/test/replace as needed.

it acts like a dead battery. the first time it happened, my buddy jumped me and about a quarter mile down the road it shut up. all the lights went off then came back on and I started it right back up. It has me confused
