Went home, switched the engine off once during the trip ( no problem to start ) when home switched off the engine and try to start again but no fuel pump sound, so couldn't start. After half hour without touching the car still no fuel pump. I left the car without touching or move it. Waited one hour more, turn on key and the pump was running again"

Had the same problem , turned out to be a bad earth on the earthing bar located behind the seat back (2012 version) made good since then no problem.you could try putting another earth on the pump to see if that clears it.
