Doc here,

First determine if it's fuel or fire..

Spray a bunch of start fluid (carefully) Down the throat of the carb (Throttle open) and see if it fires..if it's Fuel..Check your fuel pump pressure, filters and primary squirter's..

If it doesn't , pull a plug, get a jump start cable, clamp one end to the battery negative, the other around the plug base, plug the wire in, and crank, look for a BLUE spark..If not, check the dura spark box and/or module they could be going thermal and shutting down when warm..BE sure the block, dura spark box and battery are all on the same ground buss..(assuming this is in a wood or fibrglass boat..)
