I am not a mechanic however I had a similar problem with the same symptoms. I actually had it on two different boats. I narrowed it down to the gas station I was getting my gas from. Something about that gas made my motor shut down about 20-30 seconds after getting on plan. I don’t buy my gas there anymore and have not had a problem since. Good luck.
