Adding to the line count...
I would also(if you haven't) still check the coil and alternator values under load. And I would check voltage values at the fuel pump before moving on to checking the fuel pressure. I have had (even on my current car) a loose connection at the fuel pump which causes inconsistent delivery, and therefore unpredictable operation. It's worth checking at any rate.
Always possible it's something mechanical, but sudden failures like this are more often electrical, at least on the 99s I have had.
Check everything you can with the electrical components. If you don't have lambda, then you should still check the action of the aux air valve (and check that the voltage it's receiving is correct), and check the voltage at the warmup reg.
regards,
Rowan
