PO335 Fault in 2005 Nissan Sentra 1.8: Engine Stalls and Check Engine Light Persistent

A week ago, my 2005 Nissan Sentra 1.8 experienced random engine shutdowns while idling. The vehicle would stall unexpectedly and require several minutes to restart. After checking the diagnostic code, I found it was PO335 — indicating a crankshaft position sensor issue. I replaced the crankshaft sensor as recommended, but the check engine light remains on, and the car has now stalled approximately five times, typically after driving 20+ minutes. Rechecking the OBD2 code post-replacement still shows PO33 or PO335. While some online forums suggest electrical issues may be at play, I'm unsure where to begin troubleshooting. Any advice for diagnosing or resolving this persistent issue with the crankshaft sensor and engine stalling in a 2005 Nissan Sentra 1.8 would be greatly appreciated.
