Then died completely. I played around with the upper fuel filter and she re-started and ran perfectly for another hour.

I got home, changed seperator, cleaned upper filter (it is only a screen) and added some stabilizer to the gas.

Took the boat our Sunday. (we run on the Hudson River down here in New Jersey). We did a 60 Mile Run up the river. About 55 miles into the ride, less than 5 miles from the marina (right in front of the Indian Point Nuclear Reactor for anybody that knows the area) running along at about 25 knots and same thing. Just died, like it was runnning out of gas. This is after almost 3 hours of running. Started it up, and it would only run up to about 1400 - 1500 RPM, but then after about 5 - 7 minutes, Died Out again. I took a wrench and tapped the fuel line by the upper filter (screen) and she started up and ran like a champ. However at that point, the water was getting rough and I did not want to chance another stall.

So, any thoughts ? Could it be dirt in the tank that gets sucked up after a few hours of running? Could the float in the carb be hanging up, then when I fool around it drops back. Why would it run flawlessly for hours and hours, then die?

I am at a loss. Anybody want to buy the boat, it is getting that frustrating.

Did you check the carb for condensation? I ran into that issue a couple years back on my old boat. The condensation would build up and it would run fine for a while but then stall out.
