In my case, my metal fuel line between the tank and engine was clogged almost solid. I had my tank cleaned out but the metal fuel line under the car had to be replaced because the dirt inside has practically solidified. Before it was replaced, my car had a hard time maintaining high revs.

This could be the same with your car.
