I have a 2007 Honda 680 Rincon, recently on our backwoods excursions its been losing power, sputtering and backfiring. At first it seemed to only happen after I would drive through some water but the last time it just did it after an hour or so of running. It will sometimes correct itself after sitting for awhile. Anyone have this happen, I don't like the idea of being stuck 15 km out and have no power, running at 5 km/h to get home.
