I installed LED downlighters in the kitchen 12 months or so ago and all
has been fine until recently when one of them occasionally turns itself
off after a while and then back on a few minutes later.

Is it a sign of imminent failure, or could it be something else such as
overheating? The space above it is clear...

Sounds like a failing power supply.

They're mains voltage... or do you mean the internals?

Is the roofspace subject to solar gain? It could be getting hotter
in last couple of weeks than it's been before, causing a light to
overheat.

Well are these ones working of transformers or mains ones, but either way
have you tried tapping the dodgy one when it goes off to see if its just a
connection issue?
After that swap the device to another place and see what happens, if the
same location still does it the light is ok and its wiring or transformer
related, if the fault moves its the bulb or whatever leds call that bit!

the power supply is inside the bulb in those.

Most likely a dry joint, cracked trace etc.

I'll try some tapping and moving...
