Thanks for the additional info.... did you check for codes...?
If there are no codes to point you in a certain direction, then it's back to basics.... compression, fuel, and spark.
By your description, we can probably rule out compression.. for now....
Take your pick... start with one... spark or fuel... If satisfied its good, then move on to the other...
I would pull a plug right after it dies to see if it's wet with gas.. If it is, I'd probably move on to spark.. if not, I'd get a gauge and check/watch fuel pressure as the key is turned on, as it starts, and when it stops. They make gauges that fit between the tank fitting and the fuel line to the fuel injectors... it allows you see in real time what the fuel pressure is doing...
There are also spark testers that fit between the spark plug and plug wire... again, allow for real time visual evidence of a spark.
Once you figure out which one is lacking, then you need to find out why...
Without a code, you need to work from A to B with no shortcuts.. be thorough, be systematic, and be persistent... you'll find it..
Good luck and report back what you find...

You can disable security with the dealers Digital Tech II, or one of the aftermarket tools that do much of the same ($$$$)....
But I believe if it was security acting up, it wouldn't start... or even crank for that matter..
Hate to sound like a broken record.... but have you checked codes yet....?
