When I turn the key on I can hear the fuel pump prime up. I say fuel pump cause that is what I first thought it was but I am not sure. I replaced the the fuel filter. But the issue I am having is that my car just shuts off going down the highway and it will crank back up if I let it sit for 2 or three minutes. Everybody keeps telling me its the fuel pump but I am not sure what is making it do this. Any advice would be great I really want my car running good again.

Only does it on highway? When it quits, a fuel pressure test will tell you if your pump is ok.

Its only when the vehicle is moving its never when it is idling. I guess I am gonna test the relay and check the ground tomorrow. I am not very good at mechanic work, but I am kind of learning as I go so any advice would be most appreciated.

Is it sudden death quit or stuttery die out? Generally spark quitting is more abrupt then fuel pump quitting.

Crank/cam sensors are notorious for such behavior.

Separate sensors. You didn't say which motor you have.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
