Does this happen on just one ring or all rings?
Is it just the one ring that does off or are all the rings off?
One assumes this is an electric hob. Please confirm
Please advise the model number.
Please confirm you have done a Google search for something like "beko hob shuts off" or better still, a search string involving your model number.
