This past Sunday my 1999 vintage Yamaha 175 2 stroke, which normally runs like a Timex, started stalling. It fires right up and then quickly stalls. I tried all the tricks I know, including checking the 10 micron water filter for water (none present). I also tilted it up and down in case it was flooding. I recently filled the under floor gas tank to capacity, so I may have bad gas (but I added Sea Foam) or possibly I am getting a vapor lock since the tank is so full. Anyone have any other ideas, excluding the obvious possibility of clogged fuel line due to ethanol?

First thing I always do on a Yamaha not running right is the manual fuel pump diaphragms. Check or replace them and go from that.
