No engine, no power steering, no lights, no hazard flashers

While waiting at a light, car lost ALL power. No engine, no power steering, no lights, no hazard flashers. Had to put the car into neutral and push it off the road and into a nearby parking lot. Attempted to resart, heard a weird clicking from the ignition, almost as if it was "resetting", like when you put a tape in a tape deck, but would not start. Opened hood, wiggled a few wires and the dome light came on and the chime indicating the door is open came on. Car started and I drove to the mehaninc. Thought it was a loose wire, tied down all wires and checked the battery and all connections, all were fine. Car drove fine for a few days and just did it again while pulling into my driveway. I also have an automatic starter, but it is currently disabled. This is dangerous, as I cannot gwete off the road and I have no flashers to warn people I am there! Please help
