"Hey Tom, I'd be interested in what you find out. My van did a similiar
thing on my trip to see my parents over the Thanksgiving holiday (3 hour
trip). It would gradually lose power until I could only do about 35 mph. I
pulled off the road, it would rev up okay, but wouldn't pull very=20
well. It finally after a few minutes went away and then 30 minutes later,
it did it again. This time I turned the Van off and when I restarted it
worked fine... My wife has had this happen once or twice since she starting
driving it, we figured at that time it might have been water in the gas,
now I'm thinking fuel filter... However, as luck would have it, it worked
fine all the rest of the way home that evening..

        I might have experienced a similar phenomen (although Jenny is a 2L
aircooled westy) where I thought maybe fuel filter etc. It turns out to be
bad points and condenser. I haven't picked up Jenny yet to verify that the
problem disappeared.
Maybe another area to look into...
