No hot water in shower

3 yr old new build, shower never been great. Hot water stopped coming out of shower tap but does come out of the bath tap and other taps in the house. Changed the cartridge, no improvement, so put original cartridge back in. Then couldn't turn shower water off so had to isolate the water to the shower. Hot water bath tap pressure is now less since isolating shower. Bath has an anti scald / blending valve. Can anyone give me any suggestions on what to try next?

Hot water in shower keeps going cold

The hot water in my shower keeps going cold. It starts off hot but then after a couple of minutes turns cold, turning the shower off then immediately back on heats the water up again but still goes cold after a couple of minutes each time. The shower is plumbed, not electric, and all other hot water in the house runs fine. I changed the shower head recently but only swapped the head and hose which comes out of the tap/temp control, didn't touch any of the feeder pipes etc. When the showers running the boiler fires, but turns itself off after a minute or so, as mentioned it doesn't do this with any other hot water taps in the house. Any ideas on what could be the cause?
