800 lost power after going through mud puddles?

Was in West Virginia last weekend. My 07 Outlander 800 did great until I ran a trail with a bunch of water puddles (ankle high, nothing crazy). Hit those holes well enough to get the machine, me, etc pretty good and wet. Stopped for a drink and to regroup and started up again. I hit the gas and the engine "bogged" hardly moved. I had to climb about a 12 foot hill with a good rock near the top....the engine revved, the quad straddled that rock and sat there...

I managed to get over the rock and headed home -- after about 5 min of riding down some long downhills.... the power came back. Engine revved louder, power returned... ran great again.

No lights came on, ATV has 2600miles, regular oil changes, general maintenance (mostly at dealers). You're talking to a severe rookie when it comes to working on these things. Just had the dealer look the whole machine over in September before plowing season. Any words of wisdom?:th_smiliefrustrated
