Still sounds like a bad Cancel Cruise relay, Jerry, but I'm far from an expert. Since this has now seriously become a safety issue, I'd forgo turning the CC on at all until you get input by contacting 1) Vehicle Improvement Products http://www.vipwheels.com/technical-support

In DC electrics, intermittent operation is commonly a sign of a bad connection, not a short circuit somewhere - in that case a breaker would have blown (like the fuse you were looking for). That's why I suggested a corroded or sloppy relay connection, but in electronics like this where there are multiple control modules involved, like the engine, tranny, and the VIP ECU itself, there are numerous possibilities, not to mention one of the Smart Wheel switches or something.
Just after our marriage in 1980, my wife piled her two daughters into our month-old Honda and headed east on I-84 to visit relatives in Idaho. When she opted for a break at Rufus and got on the downhill off-ramp, when she touched the brake the Cruise Control wouldn't shut off. At the ramp bottom she could not stop, crossed the cross-street, swerved to avoid a crossing Class C motorhome so she couldn't go up the freeway on-ramp on the other side, and rammed nearly head-on into the guard rail on the other side of the cross-street. I nearly lost my entire new family, and the car was totaled. Tough little bugger though, that '80 Accord; we replaced it with an '81 Accord since its impact system saved our family (the cruise control was the dealer's fault, not Honda's, although we didn't put CC on the second car). Forgive me if I don't trust cruise controls, although they are much more sophisticated now. Separating the engine from the transmission was not something that occurred to my wife in her panic, but we now know it probably would have saved the day - as it might have saved some of the Toyota fiascos in recent years.
So you see why I hope you simply stop using the cruise control until the pro's weigh in or fix it. I do use the cruise on all our rigs now days, but with special due concern, perhaps some faith that modern ones are more reliable, and options in the back of my mind in case the system fails to shut off when it should. Together with other practices, the CC prevents the relatively unsteady human foot from micro-wasting fuel over long hauls. The wife rarely if ever uses the cruise control on any rig, but doesn't get nervous when I do.
