Check Fuel pressure... Could be a bit down making it run lean.  If nothing 
else, have someone (or yourself) go thru the chip and find the 
"acceleration enrichment" and bump it a bit to give a bigger accelerator 
pump shot.

Losing power when warm would be because the aircleaner lid is flipped 
over... Now you suck hot air in to the intake which reduces power...  You 
want a cold dense charge of air for power.
