The lost of brakes is puzzling here. The only thing electrial in the brake system is the ABS and brake lights. Lost of either would not keep the brakes from functioning. Lost ABS would only effect the anti skid function??

loosing the brakes would not have anything to do with the electrical
U will soon run out of air and then NO brakes but your rear brakes will dynamite on but Iam sure your able to pu;; off the road before this happens/ your power steering gone soon as engine shuts off
Question? what happens if you then turn the signal off does the engine refire right away?

If the OP's system is like mine and reacts the same, then yes he loses his power brakes and steering. Mine resets after about 90 seconds. Thus, he is losing all power including lights, etc.
And yes, hope he does post updates.

I agree with Dennis. I think you have a short in your harness somewhere in the steering column.

What is so puzzling about losing everything. When the engine dies you will lose power steering, air brakes.

After changing a brake light bulb, my CAT would quit running. With help, I found a short in the light socket.

I think Denny may be on the right track. Ford also grounded part of their ECU on the 90's Thunderbirds through a taillight. A burnt out bulb caused all kinds of problems. Corrosion or an incorrect bulb could be the issue in this case. Have you had any light bulbs replaced recently?

On the question of loss of air brakes when the engine stalls or quites please reference Subpart B - Federal Motor Vehicle Safety Standards standard No 121 air brake systems and perhaps you can understand the safty build into air brake systems. So in the event the engine does quite or stalls you do not lose your brakes.
Please think about this: If you pull up behind a heavly loaded 18 wheeler at traffic light on an up grade and he stalls his engine when he releases the clutch he is not going to coast back into to you because there is still air in the air tanks for the brakes to fuction. Even if that fails and the air pressure drop below 40 or 50 lbs the springs brakes will setup.

Gasman2, it is true you still have air in the air tank and have brakes for a couple of applications. Eventually you will run out of air and the spring brakes will lock up the rear brakes only. If the coach is going at 60 mph on a long grade down hill and if the engine dies it would be almost impossible to steer without power steering. Your brakes would eventually stop the coach, but not with air.
