Q: Reduced engine power

My wife and I were leaving the movies, I started the car and as I was pulling out of the parking lot, a reduced engine power warning light came on along with the check engine light. White smoke was coming out of the exhaust with a strong smell of gas. I immediately pulled back into the mall parking lot and turned the engine off. I called a few people I know for some answers on what the problem might be. I started the engine to see if it was still doing the same thing and again the reduced engine power light came on and white smoke with the smell of gas. I turned it off again. We sit there for 10 minutes expecting to have it towed. I decided to move it to a better location for the tow truck. I started it and no warning lights came on and it drove like brand new again. The check engine light is still on so I drove it to Autozone to get the codes for the problem. The codes were P0087 Fuel rail low pressure, P0302 cylinder 2 misfire, P0304 cylinder 4 misfire, P0306 cylinder 6 misfire. Help
