I see a few views but no replies so I guess I will dive in the deep end. At the time your vehicle dies, I would check spark, fuel pressure and injector pulse.
That hopefully will give you a starting point. If you have no spark and no fuel you might have a loose PCM ground?

maybe check your mass airflow sensor and see if the lil resistors are dirty, or maybe it needs to be replaced...try unplugging the mass airflow sensor and see how it runs, it should run, and use the map sensor as a secondary to metering airflow.

This problem started and then you replaced the fuel pump? In rare case's fuel pump relay gets hot and does not work cools off and works. How about power when it is running, does it run strong? Maybe catalytic coverter plugged? I just took one off my 1999 camaro and there where pieces that could bounced around and stoppped up the outlet! I did not have the same problem but, you never know.

The fact that it happened around a oil change is probably just coincidence. I also second unplugging the maf when it shuts off after being warm.
if that doesn't work, id check that its getting spark. Unplug the spark plugs and check if their lighting up when you crank it over. If so then id figure its the fuel system. Good luck and let us know.
