Intermittent sudden power loss on 2001 1.9 TDI Golf

Hi-
Driving home last night in really awful weather on a freeway - rain, wind, spray, the works - the car started to lose power intermittently.
It kind of feels like my old TD did just before the turbo seized, although I hope that isn't going to happen on this one as it has a FVWSH, so should have had regular oil changes and only has about 100,000 miles.
It became more frequent until it was pretty much constant. The car struggles to rev above 2500 -3000 rpm under load, and feel sluggish and restricted. Occasionally you feel the power stutter back in for a moment, but it's rare.
It may be coincidence, but what could cause this that is water related? I wondered about the paper air filter becoming sodden - but some searches talked about failing air mass sensors - could this be aggravated by water?
Other stuff I suppose is a loose hose - does this one have a hose from the manifold to fuel pump like my TD did to increase fuel under boost?
Also, I guess it could be a wastegate problem. On my TD, loss of boost was caused by an EGR solenoid getting stuck open - does the TDI have the same?
What else should I look for?
I have a boost gauge I could try - what pressure should I be seeing?
Thanks!
