It almost sounds like you are describing narcolepsy/cataplexy.

It's possible Duke is having some sort of seizure, muscular or other neurologic issue if he suddenly stiffens, falls over, or otherwise seems to be fainting.

Your vet may also recommend a referral to a neurologist if something apparent can't be found.
