90hp Suzuki Cutting off

[32RACER]

I have a Suzuki 90hp 4stroke that will run fine but for no reason cut off. You pump the fuel bulb and it will start right back. If you pump the fuel bulb it will not even cut off. Sometimes it will run 20 miles and cut off and other times it will not run 1 mile before it cuts off. I can tell you the things that I know are not causing the problem because I have all ready changed them. I have removed the fuel tank and emptied all the gas. Pulled the fuel pickup all the way out of the tank and checked for cracks or trash. All new fuel line from tank to the new fuel filter on the motor. New fuel line bulb. No leaks anywhere. I do not know what else to check or change any ideas? Thanks!!!

Fuel pump diaphram ? If you pump the bulb and have no problems you are being the fuel pump, I would say that if you rebuild the pump if parts are avalible you should be good. The gas today is killing hoses,floats diaphrams and about anything else it comes in contact with made of rubber or plastic
