 How old is your fuel tank?  Clogged fuel tank outlet will start causing these issues.  Was it a hot day?  High ambient temperatures makes it easy for Fuel Pump to cavitate; these bubbles in liquid fuel cause loss of power and even dying.  Next day after fuel is cold again, the problem disappears.  But then you drive again on hot day, and problem reappears as gasoline in tank warms up to ambient.  Since fuel tank is downwind of radiator, all that hot air flowing by helps also to heat up gasoline.  If clogged outlet from old tank, there is no fix; you've got to replace Fuel Tank.

Driving home from WRW, the car had several (usually about once an hour) hickup events during the 8 hour drive home.  Sudden momentary loss of power and then back to normal.
The Bus is a 90 with original 2.1, so it already came from the factory with 025.906.302 which is the supposed fix for Vanagon Syndrome.  
Is it possible that the little pigtail went bad?
