I am having a difficulty with my outboard, when we were out hunting at the boat ramp we put the boat in and she ran fine until 5 min later when she shut off.. i kept trying to crank it but she would run but wouldn't hold it.. videos here: https://youtu.be/ngtbzP8qggg

It does not look like your motor is pumping water. Do a compression and spark test before anything. Report back the results the spark needs to jump at least a 7/16" air gap and compression should be over 100 psi.

If you manually pump the primer bulb, will it keep running? If so, the fuel pump likely needs some attention.
