Welcome to 2CarPros.
I suspect you have two different things happening. The P0301 indicates a cylinder 1 misfire, so I suspect the piece of rubber you find belongs to the insulator on the coil pack. That would allow it to arc and misfire.
Now, the stalling when warm sounds like a bad crankshaft position sensor. Take a look through these links to better understand its purpose, symptoms, and in general how one is replaced.

What to do is check if there is spark to the plugs when it won't start or using a live data scanner, see if there is an RPM signal when cranking. Here are a few more links you may find helpful:

If you determine the crankshaft position sensor is bad, here are the directions specific to your vehicle for removal and replacement. The attached pictures correlate with the directions.

NOTE: If reinstalling the sensor, check the sensor O-ring for damage and replace if necessary. Lubricate the O-ring with clean engine oil before installing the sensor.
1. Push the crankshaft position (CKP) sensor into the transmission case with a twisting motion until fully seated.
CAUTION: Before tightening the sensor mounting bolt, be sure the sensor is completely flush to the mounting surface. If the sensor is not flush, damage to the sensor mounting tang may result.
2. While holding the sensor in this position, install and tighten the retaining bolt to 9 Nm (79.5 in. lbs.).
3. Connect and lock the electrical connector to the CKP sensor.
4. Connect the negative battery cable and tighten nut to 5 Nm (45 in. lbs.).
NOTE: The Cam/Crank Variation Relearn procedure must be performed anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components See: Engine Control Module > Programming and Relearning > PCM/ECM Reprogramming
+++++++++++++++++++++++++++++++++++
If the sensor is replaced, the relearn / reprogramming will be required. This will require specific tooling to be done and you may not have the scanner to do it.
Let me know if you have other questions or need help.
Take care,
Joe
