Toyota Repair: Cruise control drops off without warning, toyota sr5, cc computer

Question
We have a 1993 Toyota SR5 4X4, 5 speed V6 pickup. While using cruise control, during freeway driving, it suddenly drops and the dash "cruise" light blinks 5 times. It will not allow a cruise reset until the motor has been turned off. This happens randomly, just as if the brake has been touched. We would so appreciate any suggestions you can provide. Our mechanics have provided no help or ideas on the problem.


Answer
This indicates that the cruise control is turned off by either a malfunctioning actuator, speed sensor or cruise control switch circuit, check to make sure that the brake fluid in the reservoir is up to the max mark, check the brake lights, if a brake light is out the CC will not work, if that doesn't solve the problem let me know because you will have to retreive the diagnostic trouble code form the CC computer, this is a little involved and the best way to do this is for me to send some information but I will need an email address.
