2017 Versa Note Please Help

My car has 66000 miles ( I commute 150 miles) and has been perfect until the warranty ran out. I started getting spark knock about 3 months ago. Then shortly after it would misfire ( later I would discover mostly cylinder 4) but only after about 100 miles of driving. And it never threw a code. The dealership could only find a bad catalytic converter which they replaced. They told me something else was causing it to misfire and probably dumping fuel into the cat and ruined it. But they did not know why. The next shop checked the compression and replaced all the coil packs and plugs with NGK iridium plugs. Ran fine for around 110 miles then cut off and will turn over fine but won't start. Now it has a 304 misfire code and no spark to any coils.

Just a stab in the dark...........Crankshaft and camshaft sensors. See Below:

Bad Spark Plugs– Spark plugs are one of the most common causes of P0304. Take a look at the electrodes and see if they are in good shape. Most vehicles now come with iridium plugs that need changed very infrequently. That being said, the plugs are a great place to start. Here’s a great video on how to see if a spark plug is bad.
Spark Plug Wires– On most modern engines, the plug wires are not nearly as long as they once were, but they can still go bad. Here’s how to tell if your plug wires are bad (video).
Coil Packs– Coil packs rarely go bad, but when they do, they can certainly cause P0304 in your Nissan Versa. Replacing a set can be very expensive. Here’s how to test them.
Bad Fuel Injector– If you have a fuel injector that has gone bad, it won’t be able to properly atomize the fuel and you’ll get the P0304. Here’s a good video on how to diagnose an injector, it can be a little tricky. This is definitely not the place to start.
Vacuum leak– If your Versa has a vacuum leak, it can be very difficult for it to get the right air/fuel mixture. This will cause the cylinders to misfire and it’ll throw the P0304 if the leak is around that specific cylinder on the intake manifold. It’s easy (and kind of fun) to chase one down. Popular Mechanics: How to find a vacuum leak.
Cam or Crank Sensors– This one is very unlikely, but it does happen. If the ECU is not getting the right signal from these sensors, the vehicles timing is not going to sync up and it’ll misfire.
Low Compression– If you have a leaking head gasket, bent valve, cracked head, etc.. that would cause compression to not be as high as it should, you’re going to get P0304. You should also feel the vehicle is down on power as well.

Try crank and cam sensors, when they get weak you get misfire, later they go bad and you get no spark, the ECM can't because it cannot determine the timing correctly so no spark happens.
