This thread points out the potential usefulness of the much discussed
FAQ.
A quick keyword search of my list archives came up with numerous people
who fixed a similar problem by repairing the Hall connector/wires at the
distributor. Here are a few excerpts.

Re: Hall effect sender/ engine in '90 Vanagon cutting out
...of course, if it's just the elbow that has cracked and
the uninsulated wires running thru it are what are grounding
out (which I would assume it about 95% of the cases involving
"bad" Hall senders), you can fix it a number of less costly
ways.
You can thread a piece of electrical tape under the
wires (and between the distro body). This worked for me for
25K+ miles. Then when I was rebuilding the engine, I coated
the wires in JB Weld as well as cementing the elbow in place.
That will fix the problem for just about ever...

Re: 85 GL No Spark-No Start
...the hall sender unit
consists of a collar on the distro shaft and a plate in the
distro with some electronics and then three wires connect
it to the outside system. A positive 10 or 12 volt wire,
a ground, and a signal wire. These three wires come out
of the distro thru a plastic elbow near where cylinder
4 will be sparked. This elbow is a connector socket as
well and so there are three spade connector type things
in the elbow. It just so happens that these spade connectors
attach to the wires of the hall sender plate over the metal
bodyof the distro. Thus, when the elbow ages and cracks with
use, the three uninsulated spade connectors are free to contact
the distro body which grounds out at least the signal wire. Without
this signal, the ECU and tach do not get a timing/rpm signal and thus
think that the engine is not turning and never getting to a point
where a spark should be delivered...

...It's the Hall sender folks.
The plastic connector is broken right where it passes through the
distributor
body. Inside, the plastic was split into two pieces which were just
hanging,
exposing the pin of the black wire to the distributor body. I guess
that's
why the van had a tendancy to cut out when turning corners, as the loose
sender would shift and thereby ground the pin on the distributor (duh).

Re: my van keeps dying..... Suggestions?
... I've had similar 'interesting' problems on my '86...
once was an intermittent short/open in one of the wires connecting
to the Hall sender in the distributor (this one was especially fun
to finally find)....
