To be frank, it could be one of a number of things. Considerations are, how is it with water opposed to heating. Is it 30 mins? The model is vital to know so correct advixe be given

Hi, A possible thermistor fault or overheat stat failure could be doing this and this can be tested with a multimeter. Also it could be shutting down on overheat due to a circulation problem pointing to sludge in system or pump fault, with the age of the boiler i would consider NOT throwing too much money at this boiler. This could also be a PCB fault that only accurs after it gets hot (dry joint). Expensive.. i hope this helps.
