As the car has been running fine for months I wouldn't expect many of the fuel injectors to fail overnight. It's a significant amount of work and cost to replace them. Even though you replaced the fuel pump I would recommend a quick and easy fuel pressure test. Fuel pressure testers are not expensive to buy, or you can borrow one from your local auto parts store. You connect it to the fuel injector fuel rail. The pressure reading should be between 50-55 PSI.

BTW, the CPS Crankshaft Position Sensor is a common failure item. The most common symptoms are no starts, or engine dying, but if it is starting to fail you could get misfires. Many owners keep a spare in their trunk. It's another low cost and easy to replace item to try. If you decide to try that you must buy the Bosch brand.
