Hi can anyone help, I have a potterton profile 40e the boiler has been running fine until the other morning. I turned it on and it runs for a few minutes then switches itself off then won't refire at all. The body of the boiler is hot after a few minutes of running and wont reignite until its cold again. Any ideas please.

Changed the pump today and still the same symptoms boiler comes on when cold for a few minutes builds up heat in the body of the boiler then shuts down and won't reignite until cold again.
