1999 Sburban: Cruise works sometimes and not others. It will cut off sometimes whild driving for no reason. Usually you can not get it to turn on again immediately. Days later it might decide to work. Took it in to dealer and of course it worked fine for two days...they could not duplicate my problem. Took it on a trip the next day and it would not engage at all for over 1,000 miles!!!!

This could be caused by a few problems. It could be a speed sensor, brake light switch, PCM issue... Check the simple thing first. Make sure the brake lights are not on when it doesn't work. Also, check the wiring from the master cylender to make sure nothing is shorting or broken down.
