Engine Cut off at standstill

[LukeB20]

Hi All,

On my way home from work tonight, engine started fine leaving work. Stopped at traffic lights and roundabouts etc all fine, however i stopped at a set of traffic lights off of a dual carriageway in the slip lane, and eco stop start came on and then whole engine cut off and had no power at all. Couldnt start the car couldnt move it as auto, when engine finally started engine light came on, was in limp mode all the way home. Not the first time engine has cut off. 
 

any ideas as to what this could be on a 2019 St-Line focus?

Hello Luke, since it is a 2019 then it should still be under warranty. Let Ford sort it out.
