Same here, mine sounds like it's starving for fuel. I tap the gas pedal an inch twice and it fires right up,

Possibly unrelated in helping, but do you turn the ignition key and let the fuel pump prime then push the start button? Or you do turn the key and push the start button immediately. Out of habit, I always let my fuel pump prime then start the car. I see some people who thinks its a reaction test and turn the key basically while pressing the button. My car starts perfect regardless of temps, maybe give that a shot? Or turn the key on, turn the key off, then turn the key and start it, so the fuel pump can prime, then be on while you're pressing start.

Unfortunately I've tried that the past few days and still no luck. I turned the key on and off up to 3 times and waited till the car stops beeping after you turn the key before I push the start button. This only happens when the car is cold. Once I get the car to start, I can turn it off and start it back up with almost no problems unless it sits there for another few hours.

Go to an advance auto parts and see if they can test your battery.... its sounding more and more like a low cca (cold cranking amps) battery. I could still be wrong, but if it has a slow drain then the longer your car sits, the weaker the battery... doesn't necessarily explain everything but its a start.
