Hi buddy,
I'm a bit old school and used to carbs but do you think it could have been down to vapour lock? It was a pretty hot day yesterday and if you'd been on a lengthy drive it could be a possibility. Alternatively it could be a fuel pump pressure issue.

Long shot but coilpack on the way out. When they get warm they stop working and then when it cools down itll work again?

I had a polo do this and the next day started up fine, drove up the road and cut out but started and ticked over 30miles to the workshop on tow fine

Cheap relays are prone to fail,could be crank sensor.
