Has anyone had a problem with their cruise control coming on without turning on and setting?

Yesterday I was driving home in my Dodge 3500 pickup(cruise control turned off) and my truck started to accelerate, I hit my cancel button and cruise kicked off. 10 seconds later(cruise control still in off position) it happened again, I hit the off button and cruise turned off. It did this 5 times in about a mile span. I managed to get home safely with one hand on the off button of my cruise. It was raining the day this happened.

Any ideas on this problem?
