I have a dc07 that is cutting out.

This is not a cable issue.

I replaced ALL filters without exception and it still cuts out.

I cleaned the cylcone with a complete dismantle and it still cuts out.

It sucks like a monster, as good as it ever did but the cutting out is a real problem. If you leave it for 5 mins it will go again for 5 minutes, and so it will go on.

Any suggestions. I have heard it can be a thermocouple but cant find one to buy?

It will be the thermal coupling on the motor. You can buy them separately from Manchester Vacs for about £5 if you send them an email.
