Hey all, I am new to posting but I have been a long time creeper. I have a 1996 Saab 900SE Turbo. The car has a nasty habit of randomly cutting out. There seems to be no correlation between my actions and the cutting out. The following conditions make no difference, it will die...
A/C on or off
Driving for 5 miles or some times it dies after 50 miles
Full tank or nearly empty fuel tank
Freeway speeds or city (Stop/go)
Driving hard or driving Ms. Daisy
There is no error code associated with this, occasionally I get a misfire code but, not when the car dies, I randomly got a P1172 P0300 on start up before the CPS replacement
I have the SRS light lit up but, that has been on for a long time (The car sat for two years before I bought it, the light was on since the first time i started it)
When it dies, the car does not respond to me pressing the pedal, there are no warning lights/SID indicators, and its a smooth/sudden deceleration, feels like when I pull my foot off the gas pedal.

I have replaced...
MAF
Spark Plugs
Fuel Filter
CPS
Ignition Cassette
PCV Nipple

I am getting frustrated with this car!!!:nono;

Have you searched the net for "saab p0300" and P1171? The reader itself doesn't necessarily tell you all--or even some--of the details.

As for the rest of it, are those emissions status monitors? Which ones are unready, which are fail?

My vote is that you replaced the ignition cassette with a reburbished unit, which are expensive paperweights. Remove the cassette and take a picture of it including the labels for verification, we can help. Or go back to where you got it and get a replacement.
