2000 evinrude 50hp 4stroke after engine gets hot when I get up to 5000 rpms or higher about three min I lose power and rpms drop to around 2500 to 3000, I can run it at 4500rpms and it runs fine ,and when I throttle down to around 2500 to 3000rpms for a min I can throttle back up and is ok untill I hit 5000 rpms or more for more than a few min. Is it a fuel problem?
