Having trouble hitting hybrid off a tee

All of a sudden I can't make good contact with my hybrid when I hit off a tee on a long par 3.  Weirdest thing.  I can pipe it consistently out of the fairway and most of the time of the rough with a reasonable lie, but the last few times I've played that hole and hit hybrid, I've either toe'd it, hit it fat, or popped it up.  I tee it the same height I do all my irons: just the head of the tee sticking up out of the ground.  For reference, it's the same height I tee my 3W and I haven't it that poorly in weeks.

Any ideas come to mind, or should I just say f*ck it and hit that one off the deck regardless?

From the sound of everything, it certainly seems like it's just a mental thing. Maybe hit it off the deck for a bit until you get a comfort level back. Then try to tee it up slightly again. Also, double check your setup at the tee. Maybe you are setting up differently than when you hit it in the fairway?

Yeah, I'm betting it creeps forward in the stance when put on a tee.

Thanks guys, good stuff.

I trick myself by making a small mound of sand or dirt and put the ball on that, on the tee box only.  Then hit the hybrid. Looks more realistic, and ultra traditional.

Might work for others.
