454 magnum problem stalling problem

[Tripps007]

Boat starts and runs fine for about 30 minutes then power dies when idelling. Thought it might be water in line or fuel filter, so replaced filter and put in a stabilizer...to no avail. Bilge is not full. Can't figure it out and its driving me nutz. Does anyone have any suggestions?

If you had water in the fuel, You still have water in the fuel. Adding stabilizer to the gas did nothing. If you have a water seperating fuel filter, dump the contents into a glass jar and let it sit. You will then know if you have water in your fuel.
