"Can anyone offer suggestions of why my Yanmar 3HM35F starts and runs fine ( maybe a little white smoke) for 30-90 min and then cuts out. There is no water visible in the glass filter boul and I have changed both fuel filters and bled the air in the system. At first it seemed to run better when I would turn on the supplimental electrical fuel supply pump.

Thanks for any help you might offer.. Also where is a good place to get parts for these??

Aloha

" How long till it'll restart? What do you have to do to restart? What kind of start/stop mechanism is on the engine, electric, manual etc? If it is fuel, check the pressure on the lift pump, especially if the supplemental pump helped. Trash in tank? If you shut off engine, suction goes off fuel intake, trash floats away from pickup tube/screen, voila you have fuel until trash gets sucked back to pickup. "
