Try to start the car and watch the MAF G/S or MAF Volts to see if there is airflow. That is a good indicator of a clogged CAT. Its pretty hard to meltdown a CAT like that unless your doing some risky tuning. Pops and bangs tune.
It could also be your Cam sensor. A bad camshaft position sensor may give you a warning before it completely fails. A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off. If the sensor has completely failed the car could just fail to start. I suggest looking at what the car is telling you first and get that sensor replaced
