It is a 1999 Yamaha 150. I can cruise on a plane with the boat normally just fine for a while if I stay below 3800rpm. If I go about 4500rpm or more with the boat, it will go for a little while (avg 2 mins) and then all of a sudden it will just slowly wind down and die. <br /><br />After it dies I can start it right back up.<br /><br />This has also happened while cruising slow speed (but rarely). I will be going along and 20 minutes could go by and all of a sudden it just slowly winds down and dies. Then I can start it right back up and go about my business for another unpredictable amount of time before it does it again...<br /><br />Any ideas? It has a fuel/water seperator and we have checked/replaced the filter.
