OK, so my ABS booster pump officially died this week.
I bit the bullet and took it to the vendor listed in the original post. They tested and rebuilt the unit. They found the pressure switch had failed causing the motor to burn up. They replaced the pressure switch, motor and tested. Ill get it back into the car and report back how its working.
Of interesting note they stated the pump has been rebuilt before and the armature was not the correct part. They showed me the difference. The original armature was 2/3 the size of the correct part. Quite interesting!

I installed the rebuilt pump today. Bled the pump and accumulator per Adrians 964 book and all is working. I will still need to bleed/flush the full system but the car is operable again.
Anyone in SoCal have a Bosch hammer I can borrow for a weekend?

Excellent news! Yes, that sounds like mine indeed! Do the pumps look like new?
I'll update once mine arrives, thanks again!

Roadsleeper - The owner showed me a rebuilt ABS booster pump while I was at the shop and he said it was bound for Singapore. Could be yours

Ive driven the car about 100 miles since the install of the pump. My pump now pressurizes the system in about 10 sec after sitting overnight - it used to be 20-30 sec or more before the failure.

That's good to hear, did you replace your accumulator? I replaced mine which was also on its way out. Looking forward to good braking again!

I received mine today... and the union bolt on the high pressure line doesn't fit... 
It looks like someone bored out the hole, so it is now too deep to fit the OEM union bolt (i.e., the line is loose / leaks fluid when pressurized), so my mechanic had to jerry rig an adaptor, but this is only a temporary solution... I'll update when I have more to share.

. Mine bolted right in with no issues or leaks. I have about 500 miles on it now without any problems. Keep us updated.
