Will pass the shop onto my father, he is in San Diego, so may be a bit of a trek to Burbank. Did you PM it or email me last time?
Mulling this over, what system related parts can heat up and then in failure cause the engine to die. This part(s) would also have to show as checking out "good" when cold, so the failure mode has to effectively be spontaneous and not detectable except during that exact moment of failure?
1. Subject to heat? has to get warm to fail
2. Communication related? it sends a signal, or responds to a signal that says "change something".
3. Assuming the communication mechanism is fully functioning? (new wiring).
The following parts have not been replaced with new:
1. Air Mass sensor
2., Fuel pump
3. Fuel return valve.
As an aside, the fuel rail pressure is testing as fine for (have not checked for volume) as soon the engine dies, the fuel pressure has been checked.
Per the mechanic, he thinks the engine is shutting down due to a full lean situation (when it dies, it does not stink like fuel). His other observation is that the when he pulls the plugs, they are coal black, but that is probably attributed to the fact that the engine in start up mode is running rich and the plugs never get hot enough to burn off.

Ill look to see if I have another ECU, AND if I do find one, I will send it out to you. In my ( mystery ) email I sent ( ??? ) I indicated I would send it out at no cost to you. In a bunch of box's I have, are parts Ive bought from VW shops who've gone out of business, or from sellers who sell parts from parted out Vans. Some of the parts Ive bought worked out just fine...others not so fine and that's to be expected when someone is parting out.
Give me a couple days next week to have a look see at what I may find. If I hit the jackpot, Ill let you know. In the meantime, have you contacted Bela's Foreign Car Repair ? Their located in Southern California. Ive no experience with them personally but the Vanagon Rescue Squad and Samba Members give them good reviews.
