Sudden power steering and or brake failure engine still running

It very well could be a brake master cylinder issue.
all of the 1 ton and up , 3/4 ton if diesel , have hydraulic vacuum assist brake masters. that run on the power steering pump, if one part of the system is malfunctioning , it could very well effect the part of the system.

The engine provides power steering through the power steering pump that is runnung when the engine is going and the power brakes are powered by the vacuum generated when the engine is running. To lose both togeather then the engine probably stopped.

recall on the cam shaft sensor

I suggest check this Owner Manual...

Hello deepockets4: My name is Roger and I will help with your question. With the engine off depress the brake pedal 5 or 6 times. After doing this hold down the brake pedal and start the engine. The pedal should fall about 1 1/2 to 2 inches from where the pedal was. Should the pedal not drop you have a vacuum problem. If you have a hydra-boost brake system this check will not work. A Hydra-boost brake system does not have a brake booster. This system uses the power steering pump as the assist on the brake system. With the hydra-boost system the pedal will go all the way to the floor but you would have already put your nose to the windshield. For the hydra-boost system to fail you generally will have a power steering leak or pump failure. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

Good day. Please check that all fan and V bellts are in place. Your power steering pump runs with a belt, and the brakes could be of the hydraulic type. Check your power steering pump for failure if all else fails. Hope this helps

check to be sure wiring from the connector to the trailor is correct

ignition switch electrical portoin above brake pedal on steering column

1991 ford power steering pump after replacement should be bled off.you should rev the engine to about 2500 rpm before pump starts pumping and then turn the wheel from stop to stop several times.make sure the fluid is clean .if that doesnt help u need a box.

I have had this same problem after thorough checking it ended up being a bad steering box. after replacing the box it was fine
