Hi Steve,
I had a similar problem on a full pressure SAAB 9000. With me it only happened under hard acceleration, and it was caused by the Waste Gate Controller being sticky and over-boosting the engine to the point where the overpressure switch came into play - this cuts out the engine till the pressure drops to a safe level again - hence the sudden loss of power. On the full pressure turbo's you get a boost gauge so you can see it happening, but I don't think the LPT's have one fitted - so its probably a garage job - otherwise Saab9000.com will show you how to test it yourself.

Regards

Hugh
