Had this problem on a volkswagen diesel. Never was able to explain the rational for it. Took me a couple of days to find it. Was a hairline crack in the water separator under the floor area under the back seat. Made no sense to me but was the absolute cause. Separator did not leak fuel. Defied logic in my opinion but problem ceased when i changed it. Only died out and quit on left turns that were moderatly sharp or worse. Started right up again with key every time. So you may still be looking for an air leak.
