showerforce 974-t going hot / cold

The water pressure of the shower is fine to start with. However once it reaches the desired temp the pressure drops and the combi boiler turns off. After a minute or so, the water in the shower cools and the pressure increases as the boiler re-ignites to heat the water up. This increase in pressure only lasts until the water has been heated again.

I have no idea why the boiler doesn't stay on all the time.

Please help

I actually think that the problem is with the boiler, however it may be worth giving the shower a strip down clean lube and fitting a service kit, then if the problem is still there you can have the boiler checked.
