This sounds like the advertising timing out, which it is programmed to do in the example. See this post for how to advertise continuously.

The advertising timeout is specified in the following line in main.c

#define APP_ADV_TIMEOUT_IN_SECONDS       180                                        /**< The advertising timeout in units of seconds. */

I see. Did it work before this happened? Try erasing the board with nRFgo studio and program it again as described here.
