Hello, I have a 60hp four stroke Mercury. Recently on my way back to the dock at full cruising speed the motor began to stall. I slowed to half speed and it did fine for a few minutes until it stalled again eventually stalling completely and dying and not restarting. I squeezed the primer bulb and it ran perfectly for a couple minutes until it stalled again so I had to periodically squeeze the bulb to get it back to the dock. This seems like a fuel pump problem but it seems the injectors require pressure to operate properly. Any thoughts or ideas would be greatly appreciated.
