More information required - see the post at the top of the forum. Without it you will get bad guesses and little help.
AND STOP SHOUTING.

Does water come out of the hot tap ? What is the flow like ? Does the CH work normally until the boiler locks out when you call for HW?

sorry for shouting yes hot water comes out of the tap just for a few seconds then starts to run cold thats when the boiler has cut out it mainly does it when heating is on at the same time.
