I would wager that one of the hard plastic tubes/lines running in that rubber conduit (where the hissing was coming from) has broken wide open.

The leak got bigger.
The different vacuum systems are separated by one-way valves, so one leak might not take out the whole system just yet.
When you can, follow the vacuum lines and find the leak, usually the leak is at one of the rubber connections. If you have a vacuum tester it's easier.

Since then, the car has sat several weeks because I had a surgery on my leg. When I went out last Wednesday and today, the car start as normal but I noticed, after about ten minutes, the locks would not work and the ignition key would not stop the engine.
