SOURCE: heating pressure gauge goes up
there should be a pressure rellief valve fitted.
it also sounds like the heat exchanger is blocked if the hot water is not as good as it used to be and the boiler reaches temperature too quickly then there is scale in the heat exchanger and needs to be cleaned or replaced

check to see if you have a mid position valve or a 3 way valve
the mid position will give hot primary supply to both your hot water cylinder and your heating circuit if both stats are asking for heat.
you cant really get spares for these type of valves you are probably better off changing it if it is causing problems.

You likely have a flame sensor problem.
If you can wath the ignition proccess, see if you ever notice a flame. If yes, and it then shuts downm, you have a flame sensor failure, replace the sensor and clean the flame burners and orifices.
If no flame at all, then your ignitor is failing, or you are not gatting gas to the ignitor.
