fuel pump?

the boat stutters a little as RPMs move close to 1000. its happened once each trip to the lake the last few times and I haven't been behind the wheel when it happened. first time, it started to rev then died (started right back up). second time, it revved some then dropped back down very briefly then revved again and dropped again - a couple times over a few seconds. sounds like its running out of gas.. put it back in neutral then eased into the throttle and it was fine. doesn't happen at high RPMs. haven't checked anything yet - really don't know where to start.

sound like anything to you guys?

do fuel pumps slowly go out or fail completely

Since i've had the boat, 60 hrs, hasn't had a new filter or anything done to fuel delivery system
