Weil Mclain CGA 6

Problem, boiler was working fine last season, shut it down for the summer and changed a few baseboard heaters. Now when I turn on the boiler and raise the temperature the boiler get running and in 10 minutes shuts down and only a few baseboards get hot not all of them. Then boiler starts for another 5 to 20 minutes and shutdown. It never reaches the temperature on the thermostat. What did I do wrong
