Suddenly I can not breathe, it's like ...

I'm 55 years old and it's been a long time since I suddenly can not breathe, and it makes me asleep or awake and it lasts +/- 1 minute that seems an eternity, it's like closing my throat, but only for the air intake, because the little has in the lung I can eliminate, even to see if it opens again the entrance of the air. This happens about 2 or 3 times a year, regardless of what you're doing, and it's not choking because it happens without you eating or drinking at the time of the episode. Thank you if you can guide me.
