hi..
87 Wolfsburg,
cutting out intermittantly.
Turn off key when it does it and back on quickly...you're going again.
Put in another distributor ............then it got real bad, backfiring and
cutting out 20 times in 4 miles.
tried another distributor, still cut out.
swapped in an ECU ..fixed.

so the question is,
would you care to take a look at this 2.1 wbxr ECU and see if it's fixable ?
Probalby one of those solder joints getting weak.
or several.

fwiw,
when I first got this now bad  ecu dug out of the van ..
it had never been removed in the whole 248,000 miles on the van I'm pretty
sure.
it was very stuck on the upper pins ..
and with a Z bed rear seat hard to get to easil.  .  Had to use a large bar
to pry it loose and off those pins.
Impressive it ran all those miles and years without ever being out of there
even.

and again ..
it's not the actual electronics themselves that are weak ..the chips and
those units, in my experience.
Just like I say an AFM is a weak link becuase that's where electrons and
something mechanical interface,
so it is with solder joints..
it's the mechanical connection ( if you can call a soldered joint
'mechanical' - I do ) that is the weak link,  not the electronic part
itself, per se.

 how good electronic parts are is amazing.
and their capabilities..
electronics can always transcend mechanical things and their limitations.
The possiblities are beyond limitless even.
 next thing you know, cars will run on free gravity forever with no
maintanence..
and then we'll do those conversions to our vanagons !!
