Thanks to all, our Marina sells only Ethanol free mid grade gas. I will start with the filter and go from there.

Could have been a bit of dirty fuel, or a shot of water that froze in  the fuel system and reduced flow to the engine, or if an older gas engine, something to do with the ignition.  Also a common and vexing problem in old  boats is they eventually can develop a pin hole in the pickup tube in the fuel tank through galvanic corrosion , sometimes even the tube breaks completely off.  In that case the pickup tube can't draw adequate fuel into the injectors or carb and so the engine runs slowly or quits. But will start up again when fuel sloughs around the tube.   Usually it's easy to check the pickup tube, if you have an inspection plate on top of the tank.  Something dragging on the prop also is a possibility.
