SOURCE: Blown fuses
The problem is simple and you could possibly repair it yourself. the sensor on the brake master cylinder (front side protruding down from the bottom) is shorted out. This sensor turns off the cruise control when the brakes are pushed. You only have to unscrew the old sensor and replace it with the new one. You will notice that the old sensor has has brake fluid all through out it. this is the reason for the short. BTW you will lose a little brake fluid in the process so have the new sensor ready when you take off the old sensor. I know this doesnt sound like it could possibly be the reason but it is. hope it helps

have you had the undercarriage inspected for white stains from coolant, rust stains if your system is corroded? How many miles? has the water pump ever been replaced, that would be my guess, water pumps leak while the eng is running and the hot engine evaporates the coolant, so in many cases none on the ground. Also have the system pressure tested by a shop and put on a rack to check for signs of leaking under the car.

Testimonial: "Thank you for your answer. I have not changed the water pump since I bought the car 5 yrs ago. I will check that."
I had the same problem with my 1990 P/u. It turned out to be the O2 sensor touching the underside of my box shorting and blowing the EFI Fuse
