if you had a blocked nose and you were kidnapped and the kidnappers put duct tape over your mouth, would you suffocate?

There isn't a concrete answer to this question as it really depends how blocked your nose is.  It is worth noting that if you increased your sympathetic discharge (high stress, fight or flight) which would almost certainly happen in this situation, then your alpha 1 receptors in your nasal mucosa would be activated which would result in arteriolar constriction.  This would decrease nasal secretions.  The effect would be essentially the same as taking phenlyephrine.  If your nose didn't respond enough and still was truly so blocked that you couldn't breathe through it, then yes, you would suffocate.  However, if the degree of blockage was such that you could still partially breathe through your nose enough to adequately oxygenate your blood, then you would survive.  If your nose were severely blocked but you still had some slight ability to breathe through it, you would probably panic, become hypoxic, pass out, and then you would start breathing more naturally and be OK.
