OK I have the BB Z10, Model STL 100-3, running the 10.2.1.2179 software release, done by firmware upgrade about two weeks ago. Since the upgrade, with the battery fully charged, the device will conduct a full systems reboot after 28 minutes of continuous use.. Weird right. This happened on each of the last two days while at the gym, working out and listening to music through my earbuds. Exactly 28 minutes into the workout the handset goes dead and cycles through a complete systems re-boot after which it resumes normal operations. Anyone else experiencing this problem? If so, any solutions? Thanks.

is music stored on device or on media card?

can you try to play only on device and then only on media card to see if its storage related?
