Will Bad Oxygen Sensor Or Idle Air Control Valve Cause Hard Start

I own a 2002 ford mustang gt, automatic. My car has a hard time starting after driving it for awhile (it cranks, but dies off right after attempting to start while making a bop’ing noise). i had my fuel related issue taken care of (fuel pump, fuel filter, fuel pressure regulator, etc..) electrical-wise, battery, starter, alternator are all fine. my theory are the above mentioned parts, any ideas guys? (this only occur after the vehicle have been driven around for awhile). thanks for reading.
