As I was driving today, my car all of a sudden shut off. I had no electrical what so ever. I got out of the car to look under the hood and as I shut the door, the flashers came back on. I knew I had electrical power. The car then started fine. Could this be a bad ground or fuse?

Probably a loose or corroded battery cable and if they are clean and tight it could be your ignition switch is beginning to fail as power runs through the ignition switch
