My Wife have a great 1994 Bonneville SE 3800 N\A. Once or twice every three months the car will shut of at a stop light, lose interior lights and window controls, and crank with no start, exterior lights and gauges work fine. I have checked battery terminals and have no corrosion and has dielectric grease. The problem only seems to last 5-10 minutes and then it starts and runs great. no stored codes. i have not been able to duplicate the problem with a mechanic so they can't tell me anything.. PLEASE HELP if you have seen this problem before.


Thanks
Mark

Check and clean all your battery cables, both ends of both cables.
