electrical?

What is your question?

I was driving lastnight and the blinker started to blink slowly, the headlights dimmed and went off, the radio quit working, the inside dome light wouldn't go on, the heater blower only worked on high and then quit working and then each warning light came on. All the while, the car still ran just fine. I pulled over and waited ten minutes and was then able to get another few miles before it all happened again. Finally parked the car for the night. HELP please.
