Sounds to me like you're playing decently in general, but just psyching yourself out mentally on the big points.
I know for me a problem I can run into on the big points is focusing on how much I want to win the point, and not on how I intend to win the point. "Man, I really want to win this one" doesn't actually help once the point is started. For me I started making myself forget about the outcome of the upcoming point and instead just focus specifically on what I want to do that point, and getting prepared to execute in that way.
