Been there also, the wife sat her blanket there just as I drove thru a 6" puddle at about half way thru the Rhino died.
I cranked and cranked but nothing, pulled the center cover off and it would fire right up.
put it all back together and it ran fine then 5 minutes later started bogging down real bad, I happened to look down and seen her blanket laying across the intake, pulled it off and ran great.
I felt like a Dumb ass and was glad I found the culprit at the same time because we were a long way from the truck lol
