It seems to me that you lose consciousness due to reduction/loss of
blood flow to the brain.

If it were me the first guy I'd talk to would be a cardiologist.

Brugada syndrome, which I have and have lost my medical because of, is a
condition that can cause loss of consciousness and is generally
diagnosed because of "unexplained" LOC.
