The hard core test I found for fuel pumps didn't test diesel only E0 E10 E20. The avg lifespan on those are 4000,5000,6000 hours.
If diesel is similar to gas in lifespan you are just about perfectly due for pump #2. (main tank pump).
If running on the original, that would be literally exceptional (or previous owner drove a lot of highway miles and the actual average speed is closer to 40 mph)
Stand outside there car when off on the starboard side and turn the key to on and listen under the right rear seat for the fuel pump. It should whirr for about six seconds then stop.
No whirr; for sure it's the low pressure pump. The problem is when it's intermittent. So; if you get a no start, than leave the door open so you can stand outside and listen for the pump and try several times turning the key to off then on. If the pump fires up it's either the pump or the ignition switch. (I've never heard of the ignition switch failure to cause a stall while driving but if the right contact opens it would be the same as turning the key to off)
Interesting on the quantify of pumps: the "diesel block diagram" combines the high pressure stuff into one black box: I've never worked on a diesel x5
Have you ever had a no start situation before the moving stall?
