Speed Control Springs Problems of Dodge Ram 3500

Cruise control malfunction - 2003 Dodge Ram 3500, cummins diesel, manual trans. Sept 15th, 2008, 9am I left my home at 3:30 am on my way to denver for work. I used the cruise control through the town of glenwood springs at 55-60 mph or so, then made my way into the glenwood canyon at just before 4:45 am, which has a posted speed of 50 mph. There was a construction project in the first tunnel in the canyon, so I tapped the brake and slowed to about 40 mph, in 6th gear. As I excited the construction area, I hit the 'resume' button for the cruise and the truck began to accelerate (approx 4:47 am). Soon I was going over 70 mph and accelerating at full throttle. I tapped the brake and the cruise did not turn off. . . I hit the brake again, harder this time in case I didn't use enough pressure the first time. Again, nothing. At this point the truck is running at 80+ mph and I'm coming up on a semi in the slow lane, same lane that I'm in. I had to swerve around the tractor-trailer, while at the same time attempting to shut the cruise control off, back on and off again, trying to stop the truck. As I get past the tractor-trailer I'm running well over 80 mph and I'm starting to panic. I start pumping the brakes over and over, attempting to control the trucks speed around one of the canyon corners. After 30 seconds the truck stopped it's full-throttle attack. I exited the canyon and kept driving for another 10 minutes or so, then pulled over on the side of the freeway. The engine was running at 2000 rpm. I drove to the next exit and parked. Eventually the rpm's dropped to 1500 and I shut it off. I do not feel safe in that truck at all. My wife drives the truck more often than I do, it really scares me to think if she were driving when this happened. This issue was reported to Chrysler on the 15th of sept, 2008. Chrysler case# 17902313 trucks there was a required update on the ecm which was done and currently no recalls on this VIN#.
