After sitting in traffic for a 3 mile jaunt that took 1.25 hours coming back
from Cape May, NJ today the van did some kind of hesitation. It was right
after traffic started moving again the van did this thing a few times where
it felt like the motor was completely cutting out. It did this a few times
then was back to normal the rest of the white knuckle ride home.  It was
about 85 degrees outside, BTW.  I have an '83.5 WC.  It's never done this
before and hasn't done it again since the traffic jam. I drove for 2.5 more
hours home after that with no problems.

Thoughts? Everything looks fine in the engine compartment.
