Scag Freedom Z losing rpms

I have a Scag Freedom Z 26hp els with about 1000 hours. Recently it has been a turd.
When I start it up and start to mow it runs and cuts great. The rpms sound exactly right going from idle to full throttle. After about 2-3 minutes it will lose rpm and sounds like it is only running about 1/2 throttle. When I throttle down to shut it down it sounds like it barely changes rpm. Any and all help is appreciated. I cut my 2+ acres every 4-5 days (clay based yard and grows like crazy) so need to get this running right.

On a side note. The mower started leaking oil out of the pan gasket recently as well after I changed the oil to synthetic. Not sure if this problem could be related.
