You say you take the lifter out and clean it and reinstall it? You have to pump them up BEFORE you install them. If they run out of oil, they will collapse.
Given what I read. Do like DriveRider said and check oil pressure!
I have seen NO MORE than 2 go bad in one bike. But having over half bad. Would be the first unless something else is causing the problem.
