I was on the expressway today when my ABS and TRAC OFF lights came on. I pulled over and turned off the car. Once I turned the car off the dashboard lights and CD changer lights began to flash as if there was some type of electrical short. As the lights were flashing I tried to start the car but it would not turn over. After the lights stopped flashing, which took about 15 seconds, the car turned back on. Everything seemed okay for a few miles, then the car stalled when I came to a stop at a stoplight. The dash lights and CD changer lights flashed again. Then I was able to turn on the car and drive the rest of the way to work. Any thoughts on what the problem could be?
