Thanks! That's a real gem. Did it set a code when it died?

Since I always had good fuel pressure when the key was turned forward and during the times it was running, I think I can rule out the fuel delivery system. Given that I'm not restricting airflow, that pretty much leaves spark. I haven't yet checked if I'm getting spark, but by the process of elimination, that HAS to be the case, whether it's because the ECU is turning it off due to corrupted sensor data, or it's just plain not being generated for some reason. However, I've had my laptop scanner hooked up to it (TunerPro RT), and the MAP sensor readings look normal, the coolant temperature looks good, and other parameters I can make sense out of seem to be OK Next time it dies, I'll look to see if a code get's set.

I think there's enough circumstantial evidence at this point that if I can catch it failing to deliver spark during the stall, I'll just replace the distributor.
