Ford F-100 Engine Sputter

It Runs Fine At Ideal But Sputters When I Go To Take Off Why?

Having An Issue With My 1979 Ford F-100. When I Drive It, It Works Fine For The First Few Miles, And Then All Of A Sudden It Starts...

If Runs Pretty Good Until I Get It Up To 45 Then Give It Full Throttle It Spits N Sputter What Could Be The Problem

My Ford 390 With A Holley 500cfm Sputters Badley When Under A Load And Acceleration. But Idles Fine. Any Ideas Changed Accelerator Pump....
