Ok here's the problem. Stopped somewhere for ten mins and when i came out car had no power. Had it jumped then while driving power was coming and going un til the car stalled. Jumped it again and let it set running for five mins.everything looked good so drove it home. At that point was thinking the alternator was bad. On the way home car stalled within a couple miles of the house. The car had no power wouldnt even do anything when I turned the key. Had to wait 30 mins until I could jump it again but didn't need to because it had power and started up fine. Had to leave the car in driveway until the next day. Went to start it and once again no power so I pushed it into the garage. Tested battery right at 11.90 volts put the key back in to see if it would change with the key on and the car started right up. Checked the voltage again 14.01. That's where I'm at really confused. Turned on everything on in the car and still held around 14 volts. Checked the grounds all good and tight. Checked the resistance on the grounds/ power to alt all good. If anyone could give me a hint or something that's common on these it would really help me out.

Check the grounds that go from the battery to the body and the body the engine. That might not be your problem, but its a really good place to start.

All grounds are good did both visual/ hands on check and with a multi meter. One near battery straight to body, battery to drivers side motor mount and pass side body.

My fault, I guess I missed the part where you said they were all in good order.

I don't mean to insult your intelligence here, but are sure that the clamps around both terminals on the battery are tightened and not corroded?

Yeah both are clean and tight any little idea will help thought it could be something small that I'm over looking I hope it is anyway

Ok while it was in garage it works fine but when I park it in the driveway it wont. Thinking now if the car gets hot then it wont start but if it cools down onworks fine
