Ur Quattro HELP!

Ailing vehicle:

1983 Ur Quattro

On Friday, the day after Thanksgiving, I was cruising down hiway 280 
(SF Bay Area) at approx 80mph and the Seat Belt Warning Lamp began to 
flash.  The flashing became more rapid and the lamp intensity 
increased.  Eventually, after about 2 minutes, the lamp stayed on and 
about 2 minutes after that the engine and electrical systems ceased to 
function!  I was unable to restart the car, so the tow truck was 
summoned.  On Monday & Tuesday the trusty mechanics at Anderson-Behel 
attempted to ascertain the cause of the malfunction.  They were unable 
to trouble shoot the symptoms and resorted to borrowing a variety of 
components from a fellow Ur Quattro owner.  After much substitution 
they have determined the following components need to be replaced:

ECU                       $1738.00
Hall Sensor                 160.05
Ignition Control Module     237.25
Relay                       100.65
Battery Cable                37.55

Labor       `               504.00

The question that I have is:  "Does it seem likely that all of these 
components failed at the same time? If so, what could have possibly 
caused this to happen?  Anybody out there have working components that 
they are willing to sell?  According to the Kelly Blue Book the car is 
only worth about $8k so it does not make much sense to to put over 1/3 
of the value into parts for it.  I know, I know -- we do it because we 
love the cars!  But, I would like to make it as painless as possible!

Thanks
