2004 Infiniti FX35 P0011 Code: VDC Off Light, RPM Drop, and Power Loss - Diagnosis Needed

I own a 2004 Infiniti FX35 and am experiencing a persistent issue with the service engine light staying on, showing fault code P0011. I've already replaced both Bank 1 and Bank 2 camshaft position sensors, and although the new sensors are functioning properly as tested, the P0011 code continues to appear even after clearing it from the system. The most concerning symptom occurs while driving: the vehicle drops in RPM, the 'Slip' light and 'VDC Off' light illuminate simultaneously, remain solid, and then the car loses power. This happens randomly but consistently. On cold mornings, these lights come on immediately upon starting the engine. My mechanic used a diagnostic scanner and followed the manufacturer's protocol, but could not identify the root cause. I'm seeking advice on what might be causing this behavior—especially given that the cam sensor is confirmed working. Any insights or potential underlying issues related to P0011 in a 2004 Infiniti FX35 would be greatly appreciated.
