Check the settings in the ECM, they may not have it set up right/turned on.
Mine was not set when i put in a reman motor,but that my bad as the guys who put it in didn't know that as they work on Detroit motors and didn't know much about the red motor.. So i had to get it set up....but i need to get it really set up here soon by someone here to get it right. :)

Here is one example on how programming can get the cruise control out of whack ...

I could also be the clutch switch, brake switch, parking brake switch, CC buttons, tail shaft speed sensor acting up, or several other things. if the switches are acting up it can do it, or if the programming is not correct it can too.
