After running for awhile the engine loses power and will eventually quit. It turns over fine and will even fire, will not stay running. It first happened a couple weeks ago, but I waited awhile and I put some stabul fuel additive in it and then it started back up and ran fine. Yesterday I put stabul in it after I fueled up and after a while on the lake it did the same thing - ran fine then lost power and then eventually quit. Had to be towed in tis time. seems like a fuel problem or venting problem. It may also be the engine guardian system shutting it down, but I did not hear any beeps/alarms going off. I do have the single beep/alarm when first starting in neutral. I changed the oil, oil filter, fuel filter, and lower unit oil about 1 month ago. I could go out to the boat right now and it would probably start right up and run fine. It is almost like it is getting to a certain temp. and then this happens, maybe over heating (oil level is fine). But two weeks ago after it did it; it ran fine for the rest of the day. Any thoughts?
