I have the same problem. I'm fluent in most situations, but when it comes to saying my name during introductions, or if I have to tell my name to someone at a kiosk or a counter, I tend to trip up. It's not just my name, the pattern I've found until now is that I can't say the names of the people whose validation (I think) I seek the most. Considering that I'm a perfectionist who's pretty hard on myself, my name tops that list. PS: Just noticed the second part of your question about techniques to deal with it. Self-acceptance has been the key for me. If I'm happy with myself and not feeling any (self-induced) stress or anxiety, I enter this calm state of mind where I can say my name without stuttering.
