I have noticed something like this very occasionally. But I don't wait a few miles before trying it again. I can usually get it to set within 3-4 button pushes. If not, I turn off cruise control, turn it back on and then try to set it again. I've only had it really frustrate me once that I recall and I just waited a few miles like you do and then it worked.
