Welcome to the list and the 34 is a great boat. FWIW we still have original 3GM and it works like a charm
I second the thought of checking the tube. Exactly what happened on our previous boat when we changed from gas to diesel. My understanding is screens on pickup tube were common if engine was gas. Did your Yanmar replace a gas engine?

I'd also pull the fuel pick tube and see if there is a screen in the end of it, if there is one remove it - it's likely picking up sediment and starving the engine, dropping ir when the engine stops. If it that or the filters I would either polish the fuel, and add a cleaner, or remove it and have the tank cleaned.

Just brought my new-to-me C&C34 home. My 2009 Yanmar 3YM30 purred like a kitten in most seas. But this was a 30 hour slog through hell. Decided to motor-sail a bit in some heavy seas (20-25 kts), engine, at 2500-2800 rpm, would suddenly lose revs then often quit. Could start up again in a few moments, but would do it again in 5 minutes or so. Gave up on it until winds died down and started it up no problem... worked flawlessly for a 2 hour motor in calm waters after that. Boat was fully serviced in fall and on hard until 2 weeks ago when I bought and launched it. Has a Racor filter/water separator and inline fuel filter. I'm wondering if the exhaust being under water during that point of sail would cause the issue or maybe I should just change up filters, or was it probably sediment in tank being kicked up and starving the engine?
