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.
Do you

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.

It is a v6 and it is a sudden quit no stuttering or anything it just without warning dies and if I let it sit for a little bit it will crank again. I never know when its gonna die it just speratically happens.

Crank/cam sensors are notorious for such behavior.

When it happens again, check for spark.

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

He means which v6 there is more than one v6 that was put in the firebirds it should tell u on the top of the motor and another way to test for bad sensors is I u unhook the sensor and the car keeps runnin then that sensor is bad but if it dies the then sensor is good
