Sounds like there is a blockage in the fuel system. It does not take much, just a piece of lint in the fuel will block the needle. It takes a hell of a lot to strip the needle valve.

On two different planes I found that the pressure connection at the muffler was stopped. No I frequently put a needle thru it to make sure it is open..
