My 2008 SAAB 9-5 (118K miles) intermittently shuts down while driving. It will immediately restart. I've replaced the Direct Ignition Cassette, Crankshaft Position Sensor, Coolant Temp. sensor and the charge air bypass valve. Took it for a 20 mile test drive and it shut down, again. No codes Can anyone give me some other possible causes?

 

did you solve it? I have a similar problem
