I had same exact problem

I had the same exact problem on my '89 900S. It turned out to be the ignition amplifier. Try jumping the fuel pump to bypass the fuel pump relay. This worked at first for a few months as the ECU looks for an ignition pulse. No pulse, no fuel pump power.
Eventually the signal got too weak for anything else to run and the car would quit randomly.
I'm guessing the signal was too weak for the ECU but enough for everything else. 89's had a different amplifier than your year so count yourself lucky. I found just the amplifier on ebay for $65 instead of the $300 amplifier/coil assembly that eeuro wanted.
