Exactly. Remember the issues Alan L had with a metering plate that freaked out bouncing around at idle turning the pumps on and off?

I'd be inclined to disconnect the metering plate switch for testing, see if the car ran without it in circuit and go from there.

But the arm must deflect as air is drawn across the plate in order for fuel to flow to the injectors.
Agreed. What I'm thinking is, if the metering plate position was incorrectly adjusted relative to the switch (or fuel pressure fluctuation was making it bounce around the switch activation point) at idle, it might not be deflecting enough to keep the pumps running.. Then it'd die a few seconds later as it consumed the fuel/pressure already in the system.

Should be easy to check.
