What causes the cruise control to turn off?

Why is the vacuum important to the cruise control system?
As the cruise control vacuum reservoir holds vacuum for the cruise control system so that it may operate properly even when engine vacuum is low, it is very important to the proper operation of the cruise control system, and any issues with it can cause problems for the entire system.
Why does my car battery keep dying over and over?

What happens when a cruise control vacuum fails?
If the cruise control vacuum reservoir fails, the cruise control system will be left without the vacuum it requires to hold the vehicle at a steady speed or rate of acceleration. The cruise control may still try to hold the vehicle at a certain speed, however, it will eventually run low on vacuum which will cause the vehicle to slow.
How does a cruise control system work on a truck?
Some older systems, used on cars or trucks that don’t have throttle-position sensors, may have a rod that moves in and out of a magnetic coil to tell the controller the throttle position. There are also two electrically operated solenoid valves. One valve admits vacuum to the diaphragm chamber to add more throttle.
What to do if your Cruise Control has fallen off?
Aftermarket systems may resort to a ring of magnets clamped to a driveshaft or axle shaft, with a magnetic coil positioned nearby. If the magnets have fallen off or the coil has been smashed by a rock or road debris, there’s no speed data for the controller.
