I am a new GTV owner and encountered a strange, one time (so far!) performance issue. Driving on a hot day I suddenly lost power (like fuel starvation) and was barely able to make it home with a very rough ride. The next day I cranked it and it was fine (did leave a sooty deposit on the driveway after startup). The car starts quickly when cold but after warm up cranking is more difficult. I have the SPICA fuel injection. Any thoughts on where to start looking?
