2005 G35x 105,000 miles.

So as of recently, my cruise control no longer wants to work. Here are the details:

It turns on. Green light illuminates on dash. Try to set, nothing happens. Does not set a speed, second light does not illuminate.

Now here is the random part. Sometimes, probably 2 out of 5 times if I start the car it will engage within the first ~10 minutes of driving. Then, after it is set, it will disengage itself for no apparent reason and lose speed. It will not engage again. The cruise control green light (stating it is on, NOT the set light) will continue to be illuminated.

No amount of turning it on or off fixes anything. No CEL's or any other warnings/lights according to the dash and my OBD-II scanner.

This is quite annoying as I have a 100+ roundtrip daily commute.

Thanks for your help!
