I don't believe in more than 300 to 500 then replace. They can fail anytime tho. I'd check hoses first. If they are secure you need a new pump. It isn't likely your regulator turned itself off.

Makes the bottom nut not too difficult. It is not unusual for vacuum pumps to get just enough engine oil, either from the garlock seal failing or just from other leaks to introduce enough drag to cause the drive coupler to shear. I don't recall whether it was Tempest brand or other than now makes the drive coupler area protected from oil.
