My car cut off while driving. Now it won't start up but the engine turns over??

What is your question?

I was driving down the freeway going 65 mph. My car has a oil problem and an acceleration prolem. With the acceleration problem I basically have to pump the gas pedal, the RPM hits 4 or 5 then it goes as fast as I'd like. Anyways, as I was driving the car just cut off. The RPM hit 0. When I try to turn it on, the lights and radio come on and it makes a vroom vroom sound. But it doesn't start up. I have a brand new starter so its not that. Any ideas? I was told it may be the fuel pump. I also put 4 things of oil and some oil sealant because I thought maybe that'd help. Please help me!
