What does "blonk out" mean?

This may be a misunderstanding due to the speaker's accent. "Blonk out" is not an expression that is used. The speaker most likely means "blanked out," meaning to block out a memory or forget something, or "blacked out," which means to lose consciousness suddenly. The latter makes more sense considering the context (he was "found" bruised in a strange place.) Ex: He blacked out at the party and had to be driven to the hospital. Ex: I won't let you drink anymore if you keep blacking out. Ex: I want to blank out all my memories of the incident.
