1989 bumble bee. 115 yamaha 2 stroke. Launched boat ran wide open for 15 minutes stopped and put in neutral and went dead. Had to wait 15 minutes to crank then boat would only run 1/4 throttle. Any more throttle it would die. After 10 min of that it would run full throttle. Next day ran wide open for 5 min stop. Then put in neutral. Did that for 20 min then it went dead and could not get it cranked. Havent carried it out since

you MUST do any spark /electrical testing while it is dead.
compression test can be done cold.Comment
