Try replacing your fuel filter. See this guide for instructions. Use a Wix 3023 or NAPA Gold 33023.
Does it run and drive fine once it's started? No service engine soon light?

May be the gas in liquid form within the fuel delivery piping from tank to fliter and up through relief valve is depressurizing.
Start the car with the usual method which makes it stop, leave everything as is, do not touch or change anything.
Open hood and with index finger and thumb press the gas lines both feed and return...does it feel under pressure? Get back inside hit the throttle and start it, while running go back and feel the gas lines, they should be harder with fuel under pressure.
If this is the case, when was last fuel filter change? Also do a visual of the gas delivery piping for leaks. Check valve may be failing.
The throttle close off plate may be dirty, clean plus with a long tooth brush clean inside as far as you can reach inside the throttle body.
The EGR may be plugged or partially plugged, smack it with a small hammer to loosen carbon.
The idle air may be blocked, clean it.
Now clean the throttle body, including the TPS with Seafoam or carb cleaner before an oil change. Then do an oil change.
The idle circuit(s) must be clean to offer the engine a low volume gas circuit. When starting this car the throttle is kept physically closed but the idle air is open to allow lower RPM and the coolant sensor tells the ECU to allow higher RPM.
Everything works together and when it doesn't it takes a deep right foot.
Clean the idle circuits and see if that helps.
