When I owned an Atomic 4, I was told to close the water intake when cranking the engine for more than a few seconds because the waterways in the block were open at the top and would splash into the oil sump under heavy cranking. After a number of initial problems with water in the oil, this cleared things up, so I always believed it. I had a similar issue with that engine cutting out. In that case the issue was a hairline crack in the rotor in the distributor. When it heated up enough, it would distort and no longer make proper contact with the points. I sold that boat to buy my 30-2 with a Yanmar and have never regretted it! Diesels have their own challenges, but it just seems like there is a lot more to wrong with an A4.

depending on how much cranking you did, could be hydro locked? pull the plugs and see how they look and hope you don't get water out. I did have an issue with a bad wire to the coil. it seemed the wire would heat up and beak the connection somehow after running a bit and then allow it to start again after it cooled a while. I replaced the wire and it did the trick.
