Dave,
I am gonna go out on a limb here, but I know when i had bucking probs with
my vanagon it was cured by running new ground...straight from the battery to
the starter...
I never got around to removing it and clean and fix the real ground....
Could you have a loose ground somewhere that is getting sort of knocked out
of place when you go over the bump?
Just a thought...
