Cruise Control Ever Fix Itself?

[party]

I read about troubleshooting and common symptoms on user James Dean's site. It's doing the thing where it engages for a second and then quits. But it has better days and worse ones where it'll engage for about 10 seconds somewhat consistently before it gives up. Today it lasted for about 20 seconds on the express lanes and I got super excited.

This is probably wishful thinking on my part, but are there any stories of it actually resuscitating completely and becoming fully functional from this condition? The car is a '92 2.6.
