My father diagnosed with major blocks in heart artery .....Need 2nd opinion about bypass surgery...Also Is it possible to cure by pranayam?

I am 38 years old male runner and training for marathon,, but on some days while running I lose my energy and feel dizzy and unable to continue, sudden hunger and my strength completely fades for about a quarter of an hour and then I continue. I noticed that my blood pressure drops through examination (80/40) so I did blood tests, ECG, chest x-ray, sinus x-ray and everything is good. What can be the cause, and what should I check next?
