15 hp Mercury 2 stroke stalls

I have a 2000 15 hp 2 stroke that starts on 2 pulls, idles fine and runs for several minutes; after that when on plane runs fine for about 5 minutes, then stalls out appearing to be starving for fuel. Primer bulb on fuel tank is limp..runs only when I apply choke, then back up to full rpm's . Sometimes will only start back with full choke. I've rebuilt the carb and cleaned it out, also has a new low idle jet. Any help would be appreciated. Going to replace the clip on fuel line fittings next. The ones I'm using are about 15 yrs. old.

Re: 15 hp Mercury 2 stroke stalls

one obvious thing is the vent open on the tank? Next would be fuel filter? is there one of those tiny ones on the motor? I assume it's spitting water so not overheating? It sounds like a fuel constriction somewhere....
That's about all I'm good for on it.
