Apple music radio stations stop after 1-3 songs

I have been trying to use Apple Music radio stations for background music at work and home. No matter where I am or if I use my Macbook pro or iMac, every station seems to stop after 1-3 songs. Rarely will it go as long as 5-6. Anyone else having this issue?

Both machines:

El Capitan 10.11.3

iTunes 12.3.2.35
