2003 DT225 Sluggish

Had this motor since new, no probs. Went out last weekend, ran great to my fishing grounds, cranked up to come home and had barely enough power to get on plane. Once on plane motor ran good, but did not have the top end I'm used to. I thought it was the water seperator filter, replaced but no change. ALL filters are new and the gas is good, I have checked for water and found none.........Any ideas? ....I'm scratching my head here!!

Check the fuel pressure at the fuel rail.
