myson velaire standard domestic oil boiler keeps cutting out?

AFTER INITIAL START UP THE BOILER KEEPS CUTTING OUT. THE WATER RUNS COLD BEFORE BURNER STARTS AGAIN, RADIATORS ARE NOT GETTING HOT WHEN BOTH WATER AND HEATING ARE BOTH SWITCHED ON.

CAN YOU HELP PLEASE

sounds like a thermostat prob.or a remote wall mounted thermostat,or a timer prob,thats the first thing i would check out,dos;nt realy sound like oil pressure or air,if it was one of the last three the fuel lock out would cut in and it wouldnt work at all
