John Deere tractor mower slows in rpm's while cutting lawn...

Starts out great, full rpm's and grass is cut perfectly. However, after a few minutes and then periodically until I finish, the rpm's on the mower slow down and so the grass doesn't get cut properly. I have to go over these spots a couple times. Grass is not too high, or wet. Engine is at full high speed. Any ideas? There was considerable duff in the belt/pully area on top of the mower deck and that was cleaned out but I still get the reduced rpm's for the mower. Stumped in MI.
