I can't say I've ever experienced that with my E20.  One thing I have
experienced is a partially corroded relay.  With that, the relay will 
engage,
but it lacks sufficient power to stay engaged and releases -- the process
repeats, causing a clicking relay and jerky driving (I really have to 
replace
that relay).

The cruise control button simply serves to hold the speed so you can 
release the
throttle.  In most cases, the E20 has a spring-action pedal as the 
throttle, so
that makes sense.  In my case, I have a hand throttle that holds it's own
position, so the cruise control button is rather redundant.
