Engine

I was driving home from work and going down the road with my foot on the gas and it lost throttle power then the engine started shaking. I made it to the next stop sign and it died. The engine started, but with a very violent shake. It died again and had to be pushed the rest the way home. Now the car won't stay running unless you keep your foot on the gas. No lights on the dash board came on and the engine shakes bad.
