[T2] Engine intermittently turns off while coming to a stop

[Max Bronsema]

Hi again,

My bus does have the booster, I am in the US, WA state, so I have always
had the booster. I've never had issues with it as of yet. I ran through all
of the tests, except Andy's sniffer test so I'll address that one tomorrow.

Here is what I did try:

1) Start the bus in neutral with my foot depressed on the brake pedal.
There was no noticeable fade that I could sense.
2) With the bus idling, I pumped the brakes and noticed no difference in
the engine RPM.
3) I do not see any fluid loss from the normal culprits.

Still left to diagnose:

 1) Andy suggested pulling the vacuum hose from the engine and seeing if
there is any brake fluid smell.
 2) It has also been suggested to test for the vacuum from this hose, and
I'll try my best to do that as well.

Would the problem exacerbate itself the warmer the bus engine? I only
noticed it at the end of a 120 mile drive or is that just a coincidence?

Thanks for all of the ideas, it is always an occasion as we all know when
working on a bus and I am very grateful you share your knowledge so
willingly.
