Had something similar happen to my Sea Ray with a 260 Mercury. Turns out that the fuel line made one or two turns from the tank to the engine. Ran fine for a while and would then cut out. One of the fuel line attachment brackets was in a poor position and as the line warmed up, it would crimp the fuel line. Then after a while it would run fine, only to happen again. Simple fix after a lot of investigation was to adjust how the fuel line was routed from tank to engine.
