My bet is that you were being so aggressive to get close that they heard "something" in the woods and didn't want to go towards it until it showed itself. And it sounds like you were calling too much from your last post. Call less, listen more. One call and he knows where you are.
I have learned to stay back and play it slow and soft early in the year. Too easy for them to catch you moving in the woods, plus you're just learning their personalities. Later in the year, once it's greened up, that's when I like to move on birds and play aggressive. You can get away with it more easily, and with the season ending you have less to lose by bumping a bird.
