I was sitting at the store waiting on my wife listening to the radio and the car just went dead - I mean nothing. I got out of the car, raised the hood and couldn't find anything wrong, so I got back in the car and everything worked fine. It happened at my home, I opened the door and nothing, no lights, nothing. Then came on and the instrument panel would not start so I got out to see if the battery was dead and took a screw driver and checked the battery grounded battery cable to the frame with my screw driver. Sparks flew and got in the car - everything was working fine. Sometimes it just dies with no power at all. Sometimes all the dash lights will flash on and then go off but the battery warning light will stay on, but when you stop the engine and restart it goes off and everything is OK. If anyone can help, please do - the dealership can't find anything wrong.
