Driving home from work today on my 98 SE at 30MPH it died! The engine stopped, all electrics shut down and I coasted to the side of the road. It was as if I hit the kill switch by accident (wouldn't be the first time) but I did not. I checked all the fuses including the main and the battery is fine. Turning the ignition key produces no lights of any kind on the instrument panel. I had to have it picked up and brought home ($175) and not sure what to do from here. It is either really simple or really serious. I would like a shot at checking out the really simple before I try to get it to a shop. What are the possibilities?
