When I was driving a long the freeway, the power seem to cut out, the engine was still on, but with the pedal to the floor it was still at a coasting speed. Then when I came to a stop it shut off entirely. It turned over just fine, then shut off entirely again. What could be the problems with my car?

 

Could be many things. Start by isolating it to fuel or spark (check fuel pressure and spark while cranking).
