So basically, had my car for few months now and its been spot on, however it has recently started to have a slight problem, when the car has been left to sit for about 7 or more hours and i start it up, it sometimes loses power and dies, but then try again a second time and it will start up fine. Or if i turn the key to the first position only and let sit with all the electrics powered up for 10-20 seconds or so, the car will start up fine. Could this be a sensor or something. Cheers for reading, thanks in advance
