From what I can tell you are describing an issue with transitions between licks or ideas in the solo and having it "flow." The best way to tackle this is not only learning the licks or individual phrases but by breaking down the places where there are transitions between them and take time to focus only on that. It's more like micropracticing where you may only be working on a shift between positions or changing strings but this type of practicing can pay off by closing the loop on why you may not be hitting certain areas within the solo when you want to.

Hope that helps you some and if you need me to explain it better I will.

All the best,
Joe
