Original problem description:

Actually I've been told (since I wasn't driving at the time)
that it would never completely die, it would sputter and cough
and lose all power.

Upon several member's recommendations I changed the fuel filter.
I went for a short drive afterwards and the problem seems to
be resolved. I guess I'll know for sure on the next longer
drive.

Other possible causes that were suggested:

- fuel pressure (pump or regulator)
- bad O2 sensor
- bad temperature II sensor
- grounded O2 sensor circuit (coax wire shorted)
- loose or disconnected O2 sensor ground
- clogged up catalytic converter
- faulty ignition switch
- gas cap plugged up (but mine is not ventilated)

Hope these summaries help those who manage to find them in the
archives.

Thanks to everybody!
