Need Help with 150hp Suzuki Motor Stall

I am running a Suzuki 150HP, 2 stroke and every once in a awhile, the gas line would sucked in so hard that the primer bulb would sucked in, like drawing a vacuum, and no gas would get to the engine causing it to stall. Does anyone know why this is happening and what is the fix?

Thanks,

ck vent on fuel tank if built in take fuel cap off

collapsed fuel bulb means either a clogged line somewhere between the pick up in the tank and the bulb or vent issues with the tank itself, try leaving the gas cap loose. check for mud daubers nest in the vent line, trash in the tank clogging up the pick up, inner fuel line deterioration, clogged fuel filter/ water separator

if want we can check it out for you

Have you fixed your issue?
