So fuel relay pump seems to be the most named culprit. That part can be affected by temperature? Since this only happens when the car is good and hot. Thanks
This was my and many other owner's issue on the X5. Cold temps would randomly cause it not to start and it was the fuel pump relay, a small cheap $17 part and quick swap. And yes, do the cheapest/easiest fix first especially if it's only a few bucks.
And: "You can test the relay by putting 12v on the low voltage side. You will hear/feel it switch. "
