Mine ended up being the screen in the fuel tank, '84 GL Tin top.

To verify it, I took the gas cap off, then blew compressed air at low
pressure back through the fuel line.  That fixed it long enough for me to
order and get one in.  When I turned the old one over something that smelled
like gas, but looked like mud with chunks of rust came out.

Thank you Neil! No wonder Cunegonde might be clogged up - there is the tank
fuelpipe, the pre-pump white box filter, a screen in the pump inlet and also
the post-pump filter...
That's four opportunities for clogging from a 34 y/o gas tank.

Will let you all know what I find when I get underneath. And if that fixes
the fuel starvation issue. =
