Yamaha 115 won’t start

[Tpodgorny]

Message Good morning. I have a 2002 Yamaha 115 hp outboard on a pontoon boat. Three times this summer the bot have been running at idol and all of a sudden it makes a weird buzzing noise and then the engine shuts off. Then it will not start back up until the next day or so. Then it will start right up however , after 10 minutes of idoling it makes noise and shuts off again. I originally thought it was the fuel so I drained old gas and replaced and added seafoam. It ran good for a few times out on water so I though it was fixed. Then last weekend before we were going to take it out it died during idoling and would not start again. I put a new fuel filter in , checked all the hoses from gas tank to engine and all looked good. Oil was at proper level and decent color. Water is peeing out the side but not very forcefully. Looks like it has prostate issues. But not horrible. Any suggestion ? Thanks in advance
