Thought id ask on here for a neighbour who has a 05 reg Mondeo TDCi (mk3)

First thing when he goes to use it to take kids to school, he turns ignition on, glowplug light illuminates, goes out and then the car starts as per normal with no issues. Moments later, within 30 seconds to a minute as its ticking over the engine dies for no reason. He then has a orange/red cog on the dash, the glowplug light flashing, and the engine managment light come on. Car won't start for around 5 minutes, then it will start fine but you have to keep the revs up for a moment or it will die again, if you hold the revs up for a minute it then behaves as normal, doesnt die again and he can use it for the rest of the day, turn it off and on again etc like theres nothing wrong... until its sat over night and he goes to use it again the following day he has to go through it again
