Three problems related to engine stall have been reported for the 2011 BMW X5. The most recently reported issues are listed below.
Drive the vehicle on vacation and the engine would studder and stall on the highway and an error prompted on the vehicle dashboard that displayed "engine malfunction" reduced power. Occasionally the vehicle engine would cut off while on the road and needed to be towed to the dealership. The dealer diagnosed that it has a high pressure fuel pump malfunction that needed to be replaced and although the vehicle is not part of the recall it showed the same symptoms as some problematic models. This occurred while driving the vehicle on both local roads and the highway. In one occasion, I needed to restart the car to get it to a safe location.
