my bathroom lights wont come back on?

Have these lights each a separate transformer or are they operating off the same transformer.
If so it looks like a problem with the transformer,where it may be overheating. Perhaps the halogens in use are overated i.e the combined wattage exceeds the wattage rating of the transformer. If so, try using the lights and removing one/two bulbs and see if the fault disappears !!
