I have a ESP8266 wifi module connected to an arduino uno. On the ESP8266 I set up a socket server witch is working fine. And I can communicate with it as I expect.

After having run the ESP8266 some time (like 5-10 minutes) it automatically turns off (or goes into some kind of sleep mode. The LED turns off). I then have to re power the whole thing and reset it using the reset pin.

Why is my ESP8266 turning off and disconnecting from the WIFI?

Check into using wifi_set_sleep_type(NONE_SLEEP_T); in the Espressif documentation.
