The power goes on and off?

"Rotostar" - what model? Gas? Electric?
Do you mean the stove:
keeps tripping the cooker breaker and needing you to reset it?
keeps tripping the main RCD and needing you to reset it?
Randomly goes off and doesn't need anything resetting?
Is it associated with anything in particular - the oven maybe - being turned on?
When it has "gone off" is it completely dedad or just some functions?

At the moment we have precious little to think about - remember only YOU know what is going on and it is up to YOU to communicate that, briefly, accurately and concisely.
