The symptom that you're describing is a clogged fuel filter.

If it has an IMPCO Lock off, you'll need to disassemble it and change the filter if it is dirty or deteriorated.

If the fuel system uses a fuel filter, it will most likely be attached to the propane hose near the radiator.

It's easy to find.
