I had this same problem. After many months and much = towing it turned out to be an intermittent wire that connects to the top = of the alternator that feeds power back through the firewall to the ECU. = It would lose electrical contact and the van would die in its' tracks. Then, = after sitting for a while - it would fire right up and run with no problem = till the next time. It happened once right in front of the VW mechanic while I = was standing there and he found the problem immediately. I hope this helps.

Jason,This happened to me,Try pushing the plug to = ignition wires going to the Key on the steering column.I had to replace the plug.
Please help!I have a 1984 Vanagon, and I had a really = strange thing happen on my way home from work yesterday.  I went around a = corner near my house, and was accellerating up the hill, when, suddenly, ALL = of my electrics went dead (even the radio, which isn't on the ignition circuit).  Naturally, this killed the spark to the engine as = well, so I coasted to a stop at the side of the road.  I turned the key off, = waited a few seconds, then tried to start it.  The electrics came back = on, and the engine tried to crank, but wouldn't.  I then got out, went to = the back, and looked over the engine compartment to see if anything looked = amiss.  It didn't.  I then went back up, and tried to = restart it.  After a few tries, it fired right up, and motored the rest = of the way home with no problems whatsoever.My question is this:  what should I be looking for, and = where should I start to try to diagnose this?  Has anyone else on the = list had this happen?  I would almost suspect a problem with the battery = or ignition switch, but I may be on the totally wrong track there.I would = appreciate any advice anyone on the list could give me.  Thanks in advance. -Jason Stevenson
