So I've taken the 951 on a couple of long drives. To a paint and body shop. And then a few weeks later to dinner. Both times on the return home after shutting the car off for 45 minutes to an hour, the engine has starting stumbling. Slightly at first and then progressively worse. Could be fuel delivery or air/fuel mixture. I haven't heard the fuel pump getting loud but both times I almost coasted into the garage. I need to recreate the condition and check fuel pressure. I had a 280Z that would do this and that was a bad water temp sensor. Any other suggestions?
