James - aside from checking your wiring - you should be looking at your

Temp2 sensor - everyone on the list can tell you about my yearly rantings about

mine going bad for the 3rd, 4th, 5th time on a yearly basis. The symptoms you describe

match 2-5 of my episodes. The replacement sensors available are of spotty quality

and I have had 2 people tell me that even at the dealer - 20 - 50% of their are bad off the shelf.

Sensor takes 90 seconds to swap with a loss of a cup of coolant.

Here's the deal: '86 westy weekender with a rebuilt 2.1 WBX, ~40k miles on it. Have had very few issues with it until today. We drove it about 75 miles yesterday on the freeway and on some curvy, hilly roads. It ran great. Today coming back on those hilly, curvy, sometimes bumpy roads it started to cut out when accelerating...causing the van to buck a little. It started to do it more frequently, happening probably 15 times in as many miles. Gas was getting low, we filled up and I wanted to determine if problem was still there. Still happening, almost stalled at idle twice, but always catching itself and continuing to run. I checked out the engine bay, and found a small brown, ground wire that had some deterioration in the jacket...it was sitting on the block and was pretty hot. I zip-tied it up to a hose to keep it cooler, and while I was doubtful this was the culprit, I did it anyway. Couldn't find anything else that looked off...so we continued on. I'd say in the 50 or so miles after that, it happened 3 to 4 times...seeming to correspond with a bump in the freeway, although it could be a coincidence. We made it home and after unloading the van. I poked around, moving all wires I could get to while the motor was idling, hoping to find one that caused the problem. Nada. Couldn't make it happen. So...when it happens: -the engine and tach die, but it never lasts long enough for the tach to fall all the way down. -almost always while accelerating, never with my foot off the gas. -engine never completely died, and always started right up after I did shut it off. I thought it might be "vanagon syndrome", but since it happened at idle, I think that's ruled out, no? I thought it might be a fuel filter issue, and I think I'll replace it anyway. I thought it might be a ground wire issue, but can't find any obvious problems besides the one I described...which I'll be splicing a section of new wire into soon. What else should I be looking for?*********************************************
