Halstead Buckingham 4 Boiler

Hi, My Halstead Buckingham 4 boiler has stopped working. The boiler fires up, but after a few minutes turns off. Can anyone help and give me some idea what could be the fault before I call someone ? Thanks Dave

Hi Kev, The boiler fires up then after a few minutes cuts out. After about an hour I switch on the boiler again and it fires up, then after a few minutes it cuts out. Have you got any idea or suggestions of what it could be? I know it is difficult without seeing it, but have you come accross this problem before.
Thanks
