The coil itself sounds shot. You've got the symptoms.

Reference Sensor
 
The crank reference sensor
is at 900 ohms before and after the problem, so I think thats ok
I was also thinking coil, but why does it lose the 12v signal?

why does the 12volts go away?
 
Sounds like the ignition control unit--but get a real good diagnosis first--those things are mucho dinero
