Just a quick question; did you previously start it from cold but only run it for literally 1 or 2 minutes?
Because, and it's happened to me with other cars aswell, the 'over-fuel' either can get confused and can switch off prematurely the next time you start leading to fuel starvation or, because it only ran for a minute of so it has left the engine flooded and the next time you start it literally floods the engine with fuel because of the remains of the fuel that was left last time and now the cold 'over-fueling' again.... I think personally the latter because it behaves as if the engine is flooded, even sort of 'hunting' when it does start - anyway, that's my theory....
