I have had my car have a slight hesitation or lack of acceleration where it felt like the clutch kind of gave way and the car jerked a little bit, but I have concluded with a significant amount of belief it was fuel cut from running too lean.

Fuel cut is to much fuel, not too little. When too much fuel is in the mix, the ECU stops delivery and you hit fuel cut. Too lean means you have timing pulled by the ECU and there is a noticable decrease in performance (and also engine danger).
