What's the exact fault code number? I can't tell if that means a high vacuum leak or a leak in the heating, ventilation, and AV (HVAC) system. A problem in either system won't cause stalling.

Stalling as you described is typically caused by a failure of the crankshaft position sensor or the camshaft position sensor. Those two sensors commonly fail by becoming heat-sensitive, then they work again after they cool down for up to an hour or two.
