I am the original owner and car is well maintained with all needed maintenance done by a dealer. It is not a beat up car. Problem has happened 3 times in last few weeks. After sitting for a few hours at work or at a store, it starts and dies immediately. Willl not stay on unless I keep my foot on the gas pedal for about 5 minutes. Afterwards, it is fine. One time it died while coasting at about 30 MPH but started again and went on with no problems. Starts fine in the cold weather overnights. Took it to a independent service center as well as a dealer but they could not find any codes and could not duplicate problem.

Maybe because every one of them was looking for the big thing
and did not check the throtlle and or the idle air
it may just need to be clean
good luck
