On the basis of what you have said, I would now be checking that the battery is OK? What was the initial problem?

Not sure what you mean by battery running 92%. Has anyone checked any voltages? If the system voltage is too low you will get a battery warning and at least one of the two DF fault codes. Stop / start also will be disabled if the battery voltage is low. Is the alternator charging properly now, and what damage did that do to the battery before that? Alternators will not randomly stop, they are turning all the time. They may lose a field signal but more likely the problem is the battery or its connections. Check both terminals are secure, as well as all the earthing leads to the chassis and engine. Just one question.... how old is the battery?
