peugeot 206 auto gear dash lights flashing?

My peugeot 206 W'reg Auto, I was driving the car normaly and suddenly the gearbox 'S', 'Winter' lights started flashing crazy on dashboard and the car lost power, I stopped the car turn the engine OFF for few seconds and started it again... it was fine.

Could anyone please advise what could have caused it to happen and what sort of problem I'm looking at..

Thanks
