What year is it? there was an issue with the brake pressure sensor in the master cylinder. If the sensor is shorting out it will kick the cruise control off. The same could be with the brake pedal switch. The vss should be able to do it as well, if it goes out of the cruise control's adjustable range, but you see an ABS light the speedometer acting up if it was failing.

I think 99-05 had a twitchy brake pressure sensor that would fail and leak. Leaking from the pressure port could cause your brakes to feel mushy, I would definitely replace it if your in doubt, as it caused a few trucks to burn to the ground. This could also trip the ABS light.

Is the pressure sensor a seperate electrical peice or is it part of the master cylinder i may be stabbing in the dark here but does anyone know the part number of the sensor as you can imagine ford parts here in Oz are expensive so i wil try and source it in the states and get it sent over its much cheaper ?.
