that sounds a lot like the problem I had. Except I was in the middle of the delta. Left Lost Isle. Got to the house boat. Then it died.
I tried everything before a fuel pump. ... Mostly, because the fuel pump was a lot more expensive. Anyway, I finally bought the pump, and then it started. I filled the pump with fuel, before installing it. Even still, it took a long time, before the fuel made it through the system. I was worried that I still hadn't solved the problem. I was pouring fuel down the carb. Then after about the 4th or 5th time, it ran by itself.
Hope it all works for you, but with those symptoms, I say fuel pump. Could try to change the fuel filter first (probably needs changing anyway, & it's $7).
