We'd have to see why your runs are ending before you get through one rack. It could be inexperience knowing when to smash into a problem cluster and when to pick them off one by one with careful positioning.
The trick of 14.1 is to learn to recognize which 'easy shots' really are just easy shots you can just quickly clear out of your way to work on the rack, and which 'easy shots' are actually vitally important to get perfect on the leave to open up problems or get set up for the end of the rack to keep your run going through to the next rack.
My guess is if, as you say, you have trouble getting through more than 4/5 balls in 9-ball against the ghost (I'm assuming a 9-foot table), your ball-making and position play is not where it needs to be for the maneuvering you need to reliably go on runs in 14.1. You'll have to diagnose whether it's because your stroke isn't working to get the cue ball moving along to where you need it or if it's because you are making the wrong decisions about how to get shape (many novice to intermediates make the mistake of drawing and stunning everywhere when follow + spin off one or two rails can keep shape much better) and that's important in 14.1, being comfortable with every possible method of CB control, to make sure you see and can execute the most efficient patterns for your out.
15-ball rotation useful practice for almost any type of game, so if you hit a roadblock at 14.1 try 15-ball rotation to keep your control up where it needs to be, newcomers can be deceived by 14.1 thinking that it should be easier than it is and forget to maintain maximum control over positioning and shot speed.
