Crank no start issue

I drove my car up to my house to clean it, I finished cleaning and then parked it. I went to leave my house and the car started fine but I would shift into drive and there was no power when I pushed the pedal down. It was like it was idling. I shifted back into park and tried to rev the engine and was still idling. I let it sit for ten minutes with the car off and tried to start it and it would turn over but it would not start. I put oil in thinking there might be a low oil sensor from keeping it from running right and I reset the oil-r button. Still will not start. It ran fine earlier and now nothing. It is very hot outside, FYI.
