hey. My 9.9 will idle all day long with no issues. when i go at 3/4-wot for more than 15-20 minutes it bogs down and seems to lose a cylinder?"misfires" i also lose throttle control. when this happens i back the throttle down to idle wait a minute and it runs fine again? any ideas on this one? i think the red indicator light comes on when this happens..thanks for any and all advise. note. i have replaced the impeller and have a good stream of water. this was happening before and after impeller replacment..
