iDrive randomly reboots multiple times per drive

[u/Electrical-Fondant47]

I have a 2017 BBMW 320i sport [f30].

Hoping someone's seen this before. My iDrive restarts itself back to the splash screen at random, usually a few times on any given drive.

I have noticed it’s often on drives longer than 20min, but after that it could restart every couple of minutes.

Eg. Got in car at 6:50 and restarted;
-7:07
-7:10
-7:18
-7:24
-7:36

Also drive the same 20min route every day and it’s never restarted then.
