Fuel pump replaced,fuel filter replaced air filter replaced new spark plugs and a few other parts replaced was running good but now at about 30 mph it starts to blog out, help
Another possibility is a plugged cat, you can get a backpressure gauge pretty cheap,unscrew the o2 sensor before the cat, install the gauge,hold the throttle up to 2500 rpm, if the gauge stays above 2to3 psi, you probably have a plugged cat, you might get under the truck and hit the converter with your hand to see if it rattles.
Make sure all your vacuum hoses are connected and in place, also might want to check out the pcv valve usually located on the valve cover. You can also have the fuel regulator checked out... hope one of these things takes care of your problem.
