Sled starts and idles fine
Takes off great up to about 7000 rpms
After 30min or so sled bogs at 4500-5000rmps
Back off the throttle and run around for a bit, and
it takes off fine again.

Went through fuel lines, filter, etc. But problem is all
the same. It acts like some component is overheating and when
allowed to cool, all is fine again for a while.
I want to play with the rest of you.
