I have a 1990 300ZX TT, 5 speed. When using the cruise control, occasionally it will disengage for no apparent reason. There seems to be no rhyme or reason, it will just disengage as if I pressed on the brake or clutch pedal. The engine bay wiring harness was new in 2009. This problem began about two years ago and has gotten progressively worse and seems to happen more often while the load increases, like going up a long incline. Thoughts?
