Problem with my electrics cutting out - any idea why?

[Carly]

Hello!

I was wondering if anybody here has had the same problem, or might possibly know why my Yaris is behaving strangely!

Basically, today I drove a car load of stuff up the motorway (done this previously, fine) and as I'm overtaking all the electrics suddently cut out. The engine is still on but the radio goes off and the electronic dashboard goes off too (i.e. speedometer, petrol meter etc).

It happened a couple of times, just for a second or two and then it all comes back on.

A few different lights flash up, but then they go off. The ABS is always the first to flash up before they all go off. That one kept coming on, but the last few times it happened (with an empty car, going slower on the way home) all the lights flickered on and off. Braking also felt odd as if the ABS had conked out or something for a second or two.

I tried to check through the owner's manual and it did say something about electrics cutting out if the car overheats, but I'm not sure if it meant the whole car would cut out, not just the dashboard.

What do you think it could be??

Cheers :)
