Possible electrical problem? Car sometimes has no power after cranking engine
About a week ago I was sitting in my car with my laptop hooked up to the Emanage because I was making a few changes to some of the maps. Anyways I changed a map and the car died because the tune wasn't right. That's normal I thought, but then I tried to start the car again and it had no power! Nothing would come on, the dash lights didn't work, power door locks, etc... So I popped the hatch to grab a flash light then noticed the rear hatch light was on. So I thought maybe the car has power again? And yes it did and it started right up. This happened another time when I was messing around with the Emanage maps and the car died. After waiting a minute everything was normal.
Now fast forward to now... Yesterday I tried to go out and start my car. Power door locks worked, turn the key to the accessory position and the dash lights come on. Then when I turned the key one more click to start the engine, nothing. Car went completely dead. All the dash lights, radio, etc were off and had no power. I turned on the overhead dome light and it was on then slowly dimmed off. I thought my battery was completely dead or something since nothing worked, but then today I went out to start the car and it works fine.
So why is it that when I turn the key to the start the car it sometimes instantly kills the power? And it kills the power to the car for a while, but if I try it again minutes later everything is fine?
