94 Mustang GT starts great and runs good, dies after running 10 min like someone just turned off the ignition. I have noticed when it does this the fuel pump continues to run. If you cycle the key a bunch of times untill you hear the pump prime then stop then the car will start again but as soon as its ran for a few minutes it will die again and you can hear the fuel pump running constantly once again,

Are you familiar with the fuel return line? Disconnect the line and put a small gas can there. Start the car, and see how much fuel is going back to the tank. The pump may be going out. This will tell you if the car is getting a steady supply of fuel. If it is, we will try a couple of different things. Try this, and see if it helps. Are you familiar with the fuel return line?
