Try disable spark and fuel and hear how it turns if its even or jumps. You may have something warped in the engine.

It seems that it was driven for long enough to damage the engine, it no longer runs. Generally the first thing damaged is the cylinder head, next the cylinders. People notice that the engine is overheating when there is no more power to move the vehicle.
