SOURCE: lack of power
Turbo failure is never normally intermittant so I doubt it is a turbo fault.
The wastegate relys on a signal from the ECU via the MAFS.
Mass Air Flow Sensors are very common to fail on VW TDi and this also fits in with your symptoms.

Check the engine codes at Autozone or a place like that. Then check fuel pressure, change fuel filter, and listen for hissing when you remove the gas cap, from a possible bad purge valve.
Final advice is to try a slightly smaller spark plug gap, because it will not blow out the spark as easily when under load.
