Hi on your auto run it might be the way the rune itself is designed It's set to "loop until second press", then play once more. This means so long as you are pressing up/running forward, it's going to keep pressing the left stick center press. I'm wondering if the game will make your guy stop running when it receives excessive left stick presses? You might try changing the loop to "Play Once". When your guy stops sprinting you'd have to pull back on the stick and then press up again but it could eliminate your guy from stopping sprinting.
