I'm posting this because I smoked this cigar today, it was very good, but for some reason it self-ashed twice and completely blew out? I was smoking it, got to about 60% through it when for some reason ...just went out. This has never happened to me before. What gives?

(it was fresh from the B&M I get all my cigars from).
Other than that though, it was a heck of a cigar in fact I bought 3 fuentes today. Going to smoke the other 2 tonight.
