You have to play through it. I just got out of slump of sorts and excepted I was playing poorly. There is not fix or drill. You either play through it and it will click again or walk away for an undetermined amount of time.
this is what i had to do the last time i had a bad slump walked away for a few weeks. started all over from my early season shape up when i came back worked on the basics all over again helped me a lot.
