Very infrequently and unpredictably, my 2001 boxster wont start. When I turn key, sounds like everything is fine but has trouble actually turning over. Occasionally it will turn over but quickly dies. Sounds like I need to give it some gas, but when I do, the car doesnt even sound like Im touching the gas pedal. If it sits overnight, it starts in the morning fine. I got stranded last night. This am it started, but now I notice that Occasionaly when I accelerate, it feel like its losing power and hesitates. No warning lights. Took to Porsche specialty shop last month. They kept for a week and couldn't find anything wrong and of course it never happened to them. Any ideas?
