    You have a vacuum leak in the vacuum supply line at or near the vacuum storage canister which is a tank mounted just to the right of the master cylinder / brake booster. The tank could also be leaking vacuum. To explain why your symptom happens would be too much rambling, but the cause is a vacuum leak 4 sure.
