You need to do an OBD2 engine control module fault code test to see if the fault is recorded in the memory of the computer control module. Autozone and others do this testing for free.
thee are many things that cause this, first worn piston rings could cause it not to start when it's cold or the glow plugs are bad that would cause it not to start the first time, however you say one it starts and shut it off it is hard to start afterwords so this would lead me to believe you have a plugged fuel filter or a pump going out. The reason I say this is it does it only when cold so two things can happen that could cause this, the fuel would be to thick for the pump to pump the fuel or bad glow plugs, however if the engine started then and was hard to start afterwords I would suspect the fuel filter or fuel pump.
fuel pressure regulator!! located onear the fuel rail. next time after it stops , pull the vacuum line off the fuel pressure regulator. if gas comes out the vacuum line its the regulator. easy to fix , only need a snapring pliers. part is about $50 bucks.. richie
if car shuts off while driving it could be a bad crank sensor. a bad crank sensor will shut car off while driving, then it will not start for about 10 minutes, when it starts it runs fine until it goofs up again. the popping could be the sensor for it controls timing along with the cam sensor.
I think you should check your battery and alternator.If they both check good you may have a battery draw,something draining the battery over night.Check your doors make sure they are closing like they should.
possibly a bad module------cracked---or???? In any case you may get expansion as engine compartment warms up----module shuts you down. Sometimes really hard to diagnose and just putting in a new module is "spendy"----especially if it turns out not to solve the problem!
