Timing belt, electrical problem, or fuel pump. Or something else?

I was driving just fine on 94, when the car basically shut down as far as performance, the RPM's dropped, period. I made it over to the shoulder, but the car wouldn't let me turn it off after it was in park. It basically stalled itself out. When my hazard lights were on, there was a buzzing noise. My power windows don't work. My door locks won't work. My key won't come out, even when you use the shift lock. It did magically come out once, but even out, every light on my dash was still lit up. The radio also doesn't work. And then we had to put the key back in for the tow truck driver. When you try to start it, it cranks, but it won't start. I've heard : fuel pump, timing belt, and also it could be an electrical problem. (I may be wrong. But I'm thinking if all the lights can stay on without a key in [Keep in mind they're not the ones that turn on when you open the door. They're only the ones on the dash.] There has to be something slightly electrical as atleast part of a problem. Either that or my car really is possessed like Christine.) So I suppose my question is, what would you guess the actual problem(s) is/are?
