This sounds a lot like what happened to my '90 westy also on a trip to Santa Fe (oddly enough). After 2 hrs, started bucking slightly, then more and more - turned into real hesitation. I too did the capacitor fix - which also changed the symptoms. It finally died and ran so bad I couldn't drive it - until I unplugged the O2 sensor. Then started right up and ran fine. So I replaced that, and it was fine all the way back to Colorado. Now I'm having this sporadic engine cutout issue, which almost stranded me once, but fixed itself and hasn't occurred in the last 1000 miles. I'm going to replace my Hall sender, as there seems to be some broken/melted plastic in there, and from what I've read, they do fail after 200k+ miles. Seems like it must get pretty hot inside the distributor. You should also check the hall sender plug- those wires are always brittle, and the connector gets loose.

Such is the price we pay for driving 20+-year old vehicles, I guess.
