I had this same issue when I first purchased and it even stalled sometimes when trying to restart once the engine was warm, like say I stopped for gas or went into the store. They had to replace a solenoid I believe. No codes or check engine was being thrown so they didn't believe me at first. I have the work order receipt at home and will try to upload so you can see exactly what they did on mine.
Sorry, my mind was in auto land. Press the ignition button once before pushing in the clutch and pressing it again to start. See if the fuel pump being able to prime helps with the warm/hot start.
Sloppy, thanks for the suggestion. It is the same whether I press the button first then clutch or button and clutch at same time. This makes me thing its not the fuel pump, but rather is starter related. I've read about start heat soak being issues.
Thanks, thet333. That will be helpful when I take it to the dealership.
