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

I recently had the same problem, my 2002 9-5 Aero would die every time I came to a stop or put the clutch in. Replaced the Mass Air Flow Sensor and it doesn't die anymore, but it still runs a little rough when shifting and I still get the check engine light. I talked with a tech and he said that I disconnect the battery for a few hours it should clear the fault codes.

Two most common problems for this are the DIC and the fuel pump. Can also be the CPS. First check the code. You can try this first before going to a code reader: 1.With the car already off, switch on the ignition without starting the engine. 2. After approx. 6 seconds, the 'Check Engine' light goes out for an instant before lighting up again for 3 seconds. This 3 second flash is a warning that the actual flashing code is about to start. 3. The flashing code consists of a number of short flashes lasting 0.4 seconds. The 'Check Engine' light goes out for 2 seconds between each new flashing code (if there is more than one fault). 4. After the last flashing code, the 'Check Engine' light goes out for 3 seconds before lighting up again for 3 seconds, after which the flashing codes are repeated. Readout continues in this way as many times as you wish. Number of flashes / Function 2 / Manifold absolute pressure sensor 3 / Temperature sensor, manifold 4 / Temperature sensor, coolant 5 / Throttle position sensor 6 / Oxygen sensor 7 / Adaptation 8 / Purge valve (EVAP valve) 9 / ECM, internal fault If no flashing codes display, the problem is something else (other than those nine listed above) and must be determined using a generic code reader that supports OBD 1, or using the GM/Saab Tech II code reader and programmer. My money is on the DIC as it is a very common failure component and fuel pump failures rarely throw a code. The DICs are good generally to 100,000 to 150,000 miles, but this varies wildly, especially if the car is run with overgapped plugs for any length of time. The plug gap should be 1 mm and no more. Cars that are scrupulously maintained vis-a-vis the plug gapping can see DICs last over 200,000 miles.
