not familiar with Cruise Control but thinking it's a stitch regulator? If so when you get those long stitches with no holes underneath it usually means that something is wrong with the encoders that control the stitch regulator. Make sure it is all well connected and if there are wheels that roll on the carriage to feel the stitch regulator encoders, that they are working properly.
OK, just googled your machine and the Cruise Control--definitely you are having issues with the stitch regulator. Not real sure how it connects to the Juki, but guessing the problem is with that connection or with the way it reads the stitching.
