Its your knock sensor. I was having the EXACT same problem on my '91 900S (LPT now). It would be off for a long time, and then randomly come on just as you describe. I checked continuity between knock sensor wiring from the sensor harness and ECU, things were fine as expected. I ended up throwing a brand new sensor $45ish at the time, on there and have never had a problem since...
