Car Turning Off For No Reason

[Cemil cimen]

Hello, for the past few months my Toyota yaris 1.0 lt 2004 model has been turning off suddenly after all the warning lights light up. It is also accompained with a buzzing when it turns off. Before this problem happened it was running smoothly but now it feels heavy to drive, when I take my foot off the gas it slows down really fast (as if you are braking) ive sent this for a service and they couldnt find the problem, could it be an electrical fault? Thanks in advance.

If all the warning lights light up and it then stops, there will be fault codes logged.

Any semi competent mechanic can read them. I could - I have a code reader.

Not so, all the lights will come on when the engine is off, no different to when stalled, it doesn't mean a fault code is stored.
