Welcome to the forum. Is this on the ITV Hub app? In the past live channels have caused problems for some users, stopping and starting, although things seemed to have died down recently.
Try deleting the app by finding the app in the My Apps section on the homescreen, and instead of pressing OK on the remote to open it, press the * key and choose remove app.
Then remove the power from the box for a few seconds, reconnect back up and add the app again from the App Store.
If that doesn't work you could also try a forced software update by doing the following:
Press Home on the remote to take you to the home screen. Then do the following sequence on your remote quickly and smoothly
Home (x5) FF (x3) REW (x2)
If done correctly a Secret Screen will appear (if it doesn't, press Home to go back to the start and then try again). Choose Update software and allow it to run (even if it reports the same version as you already have).
