NO central heating from combi boiler?

Hi hope someone can help, my combination boiler Ideal stelrad/Sprint will not stay fired up when selecting central heating.
When I call for hot water it fires up and I get roasting hot water, the pressure is ok and no leaks, the thermostat is working, the pump is running and spinning away but the burners give up after about 10-60 seconds. Any ideas?
