Loss of power brake assistance after engine shut-off

Hello,
is there someone out there who knows the answer to my problem? Since a couple of weeks, I am experiencing a total loss of power assistance in the brake system after I shut off the engine. That means - prior to this, even after the engine was off for a prolonged period of time, there was always remaining power (vacuum) in the system (i.e., the brake pedal felt soft when pumped). Now, immediately after the engine is off the pedal feel becomes rock hard as there is no more pressure in the reservoir.
I know there must be a leak in the vacuum system. My question is how do I find the problem (which vacuum valve etc. could it be).
Although it may not be related to this, I have to crank the cold engine longer (3-5 seconds) before it starts now. Prior to the brake problem, I jump started immediately, warm or cold. I am 99% sure this is not a problem in the spark plugs or DI cassette.
Thanks a lot in advance for any valuable hint.
