instantly.

 the wires from the switch have frayed and broken.

brake and or clutch pedals.  See if it cuts out if you touch the pedals
_very_  gently.  If not, suspect the wires at the switch.

old and cracked and just needed replacing.

Having replaced all the hoses and adjusted the switches, the reason my cc
fails is when neither brake light is working (the control unit dribbles a
small signal to ground through the brake lights).  Re the vacuum switches at
the pedals, did I understand a post a while back (Graydon I think?) to imply
they are not threaded - so when I think I am turning them out a thread or
two I'm really just spinning in place?  Hmmm...
