Hi so I was driving my G for about 30 minutes and got out and when into store for about 2 minutes and when I came back out to start the car I clicked start and all accessories and everything turned on and as soon as I went to click start again and start car up it went completely dead. Nothing would work at all no lights or nothing. Got it jumped and drove home and two days later tried to start and it was perfectly fine. Any ideas on why it would be doing this?

 

Have you tried cleaning and tightening your battery's terminals?
