Why stop at 100LL, Norm, when there's nitro?
Man, these are some seriously funny posts.
BTW, the exact same symptoms happened in my 1989 VW Golf.
After going around and around in circles and throwing a few sensors and a pump at it, it just quit in the middle of an intersection while driving.
The cause?
Freakin' $60 Bosche fuel pump relay overheating. That was it.
