It just dies like you turned off the key. When watching the TBI, seems like nothing is coming out once it dies.... This is become more and more a mystery. No codes are being thrown at all.
Just realized it was my 90 Corsica (not the Cavalier) that did exactly that. I went through a detailed process to come to the crank sensor. Schematics, data sheets, oscilloscopes as well as knowledge of inductive sensors. Bottom line for the Corsica was the raw signal level would start around 1.5 Vpp and I could watch it fade as the engine warmed up. I stuck a pin through the sensor wire to creat a test point. The engine would die when the raw signal reach about 1Vpp. After a 10 or 20 minute rest it would start and the singal would be stronger, but again would fade. A bit of research revealed that there was no code on that vehicle for crank sensor faults. Service guide flow chart for "engine dies" was a very expensive list of parts that included Ign pack, ECM, etc, etc... Inspection of the crank sensor revealed a suspicious crack. I replaced it.
I hope this is somewhat helpful. If you're going for a DIY repair, find a U pull it, wrecking yard. Sensor should be less than $5.
Edit; the Corsica also had the 2.5l engine. My arm was just long enough to reach the sensor from the top drivers side by the firewall. I still have the factory service manual if you think of anything you'd like me to look up.
