Mowing GT325 engine power loss??

[kz202r]

After I cut lawn for a few min, the Kawasaki engine seems to lose power. It almost sounds like the engine drops one cylinder. Just did a complete tune up with air and fuel filters to try to fix problem but no good. Anyone run into this before??
Once tractor cools down it seems to run good untill the engine heats up.

I have same tractor ,just a thought check your fuel cap make sure its properly ventelated, might want to let idle w/cap off for a while and see if issue persist.

Thats easy enough to try, I will give it a shot. Thanks much.

No luck on the gas cap idea. Still loses power after warming up.
