when was the last time you drained the water from the filter. Is the problem present at idle as well as driving speeds??

Well found the problem seems the drain valve in the bottom of the fuel filter worked itself loose and as the surf sat over night it would loose enough fuel and pressure that it would run like crap the next morning till the system pressureized again then ran fine Anyhow just tightened up that drain and problem solved
