Fiat Grande Punto 07 need help!!!?

Driving along today when warning flashed up " check engine " then lost power ,engine still running but no response when pressed accelorator --managed to coast into nearby car park and turned off engine. Tried to re-start but absolutely nothing !!, not even sound of a dead battery trying to start. Lights ,radio ,fan etc all work but there is a warning light insignia I have never seen before-- Looks like the front of a car with a padlock over it colour is orange. Can anyone tell me what this means please,
