I have seen other posts about this topic and knowing Sonos support I highly doubt there is a response that actually works but here goes. 

I have two Move 2's set up as a stereo pair that continually stop playing 30 seconds into any song. 

What I have tried to resolve:

Restarted router

Restarted speakers

Restarted phone

Tested wifi

Re-paired speakers

Full shutoff of phone

Started from new install again (most annoying)

And it continues to happen. As I have posted before; I love the speakers when they work as they have incredible sound but the Sonos software is the worst and riddled with bugs.

Hoping there might be a fix but my hopes aren't high per all the previous experience I have had.
