what about the coolant pressure cap....no pressure and you cant pump air bubbles...you have a water pump....

also if exhaust gases are shooting into the coolant ,,bad head gasket etc...you get the same problem.

possible the cat is getting restricted...losing power?

Radiator cap could be bad. Also, you still might have air in the system. What gaskets did you change, and did you bleed the system after the change?
