Only works on high power after running on medium for 10 mins

The shower has been in and running for some time but recently cuts out when you start it on high power. If you allow it to run for 10-15 mins on medium then switch to high everything works although the red led for high is very dim. I don't believe the water pressure has fallen so would appreciate any pointers.

When you say it cuts out do you mean the water supply stops or it goes cold?

Water supply stops and all lights on the shower go out. Pressing low or medium restarts the shower.
