car will turn over when cold then will die

You need to check for fuel pressure and spark, for starters. I recommend replacing the fuel filter if not done in recent memory, first. If fuel pressure is not stable (with a fresh filter), then I'd suspect the pump. If spark fails, then you need to diagnose the ignition system.
