It's either fuel pump or the fpr going bad. Do a pressure test at the fuel rail shradder valve. It should go up to 40 psi and hold...

It's easy enough but yours is fly by wire like mine, so the butterfly does it all... Every great once in a while mine will start and die, Hasn't done it in a while. Try checking fuel pressure I guess...

Mines a stick so the constant shifting probly makes it more pronounced.
