I am working on a friends boat & here is the problem that has me stumped. He had it out on the river & it was running perfect the whole time with no problems at all. Ran all day. The next day when he went to start it it would start, run for 30 sec. & then die. You can squeeze the primer bulb after it starts & hold it tight & it will keep running fine. Any idea on what may be the problem here. Thanks for any help I can get.
