I would remove the carb and clean it look at the float and float needle in particular. You may get away with removing the bowl and checking but I find it best to bite the bullet and remove it all. Not sure what the temperature is where you ride/trailer but a similar thing happened to me it was a little water in the gas that froze in the carb. I ran gas line de icer through it and gave it a few taps with a screwdriver while it was running without removing the carb and the issue went away. As others on here will say run a little sea foam through it.

There is no reason an 700 pound machine shouldn't catwalk and drive through 6 feet of water.
