Hot engine won't restart on hot day

[ptopping]

If it is a hot day and I drive the car up to temperature and park up for 10 mins, when I try to start again the starter motor turns but no fuel is getting to the engine. If I leave it for 20 mins it starts OK. I know that no fuel is getting to the engine because it is not flooded. This happens when the outside temperature is above 25 degrees. It also happens if the Auxiliary fan has kicked in after stopping. Help please. I have also posted this in engine but my garage has tested for error codes and there where none. If I keep the engine turning there is a message on the dash that says "FAILSAFE ENGINE MODE" I have had a replacement thermostat fitted about 2 months ago.
