After driving 7 to 10 miles power falls off like its wanting to die
You need to have the fuel pump pressure tested when this loss of power is present. You should at least 42 PSI and about 50 PSI under a load or when the throttle is applied quickly. The fuel pressure test port is on the fuel supply rail on the top of engine, it is a pipe that sits over the fuel injectors. The fuel press test port looks like a tire inflator valve.
