I know you say you changed the thermostat, but it sounds like you might still have a thermostat problem. I would check the thermostat just be sure.

You might also remove your water pump and check the impeller to see if it is still moving water. Impeller blades can deteriorate over time until there is not enough of them left to be fully functional. This will result in the conditions you describe.
