Mira Sprint Mk3 running hot then cold then hot.
1 That the main valve coming into your house is fully open.
2 Then check that the valve on the line to the shower is fully open.
If these valves are not fully open then there may not be enough water getting to your shower to cool it properly, it overheats the safety device cuts in (TCO) and turns the power off to the elements until it cools down and it all starts again!
Make sure that the shower head is clean and clear, that the hose isn’t kinked (this can happen just behind the hand set where it is difficult to see) also check the inside of the hose although it can look OK on the outside it could have collapsed internally
The other possibility is a faulty flow/stabilizer valve not allowing the correct amount of water into the shower.
There is a link below that explains the above.

I've checked all the valves and they are fully open, the shower head is spotless, the hose is clear with no kinks. the water pressure is coming through fine. The shower is now just running cold even with heat settings adjusted.
Kind Regards
