Sorry buddy. Same results after a new OEM impeller and checking over water pump parts. I’m trying to remember the story of the impeller housing, I seem to remember that you have tried one from another engine as well.
OK, well how about removing the thermostat cover quickly when it stops pumping water to see if water is still getting pumped up to the cylinder head. I know you said it pumped great before you messed with it, but I’m thinking perhaps there is a head gasket leak, that would explain why it stops pumping water once it heats up. Try a compression test, any signs of water on the plugs?
Post some pictures if you can.
