Unfortunately the boat is about 90 minutes from the house. I won't be able to get down to her for a couple of weeks. I'm hoping you're right about it being an anomaly.

I believe it is carb. Like I said, I good with vapor lock being the cause of it not starting again. Well, good might be the wrong word. It was hot that day in the low to mid 90's. So that makes sense. The stall is what I'm having a hard time with. Is it stalling. I was just starting to trust it again
The reason I asked , it is an important difference when trying to diagnose a problem......you never know what a previous owner has done over the years, so it is not necessarily the engine package it was born with....

Might want to check both the anti-siphon valves and the vents for the tank.

KM,
The anti siphon valves help with vapor lock, right? This reminds me, I need to replace all 4... When i use the aux tank, which is below the waterline, after running it my fuel lines are empty.

I unfortunately won't be back down to the boat for a couple of weeks. I take a look at the flame arrestors then. My fear is it stalls coming back in to the marina. I'd have little to know hop of successfully maneuvering it in tight quarters on 1 engine.
