2001 OLDSMOBILE BRAVADA Electrical System Problems

I WAS TRAVELING ON THE HIGHWAY AT THE POSTED 55MPH SPEED LIMIT WHEN ALL OF THE SUDDEN, THE VEHICLE COMPLETELY SHUT OFF. THERE WAS NO POWER AS IF THE IGNITION FOR THE VEHICLE WAS COMPLETELY TURNED OFF. WITH THERE BEING NO POWER TO THE VEHICLE, I COULD ONLY ALLOW THE MOMENTUM OF THE VEHICLE ROLL TO THE SHOULDER OF THE HIGHWAY AWAY FROM TRAFFIC. I HAD NO USE OF TURN SIGNALS OR HAZARD SIGNALS. ONCE I WAS ABLE TO GET OVER SAFELY, I LOOKED AT THE DASHBOARD AND COLD ONLY SEE THE BATTERY INDICATOR LIGHT ON, NO OTHER LIGHTS WERE ILLUMINATED. I TURNED THE KEY TO THE OFF POSITION, REMOVED THE KEY FROM THE STEERING COLUMN, REINSERTED THE KEY AND TRIED TO RESTART THE VEHICLE. AT FIRST, NONE OF THE DASH BOARD LIGHTS WOULD COME ON WHEN I TRIED TO RESTART THE VEHICLE, I HAD TO REPEATEDLY TURN THE KEY...

THE CONSUMER HAS A ELECTRICAL PROBLEM SHE HAS NO BRAKES LIGHT FLASHERS. PLEASE PROVIDE ADDITIONAL INFORMATION. DEALER IS AWARE OF THE PROBLEM. TS
