1984 150 HP Evinrude dies when running over 4000 RPM

[quackshot]

My 150 HP Evinrude runs perfect between 3000 and 4000 RPM. When RPM's go over 4000 the engine cuts back and dies down I can go back to idle and start going again and as long as I stay under 4000 RPM it runs fine.

Did you try pumping the primer bulb when this happens ??
