Potterton Kingfisher bf

[safc]

Hello all.
Was called to a problem of no hot water or heating. Boiler fascial seemed to have no power. Checked the fuses on the control box, all ok. Once i put the control box back into position the boiler fired up ? Now it fires up for a few minutes then goes off for about 10 seconds then fires up again ? Any ideas ?

id first use a meter or tester of some kind to check its not a dodgy conection in the fuse spur seeing as that was where the problem started could also be pump failing and shutting boiler of on heat build up its quite a simple controll system on that boiler power in through stat to gas valve so just a simple test along the line to see whats shutting it of
