Unit runs much better and smoother with air filter off. Foam element is clean. When putting filter cover back on, unit looses power. At times the unit runs fine for up to 30 minutes and then just lloses power

Hi there bcolli3
does the unit become very hard to start if warm or hot but ok if cold
have you checked for restricted muffler ?-
is fuel system working properly ?
a air leak could also cause this too ---vaccuum and pressure impulses are needed to operate carb diaphrams and pump and regulate fuel mix ,
check the manifold block/ carb gasket for a air leak, check cylinder barrell to block bolts are tight
check carb bolts are tight,
check that fuel lines are ok no holes / splits , and fuel filter is not restricted / blocked,
could possibly have worn rings too
do compression test and a spark load test
