Just took out my 1994 Four Winns with a Chevy 3.9 liter engine for the the first time this year. It Ran well except at full throttle it would intermittently loose power a bit as if I were pulling back the throttle slightly. If I back off the throttle a bit it was fine. I changed the fuel pump the summer before last. Any Ideas

I am assuming you meant 3.0L. Sounds like you are going lean. Have you changed your fuel filter?

When I changed the Fuel Pump two years ago I changed the Fuel Water Separator. Is there a separate Fuel filter also?
