I was driving back from work going 25 MPH with a 1/4 in the gas tank and randomly my car was losing power and at the light it randomly stalled. I turned the car off and tried turning it back on which it turned on and had no codes and drove like nothing happened what could cause this? The only check engine light is a p0430. But something weird about the car is when revving the car when in idle when the RPMs drop the car also what to sort of stall but goes back to normal RPMs.

P0430 - Catalyst System Efficiency Below Threshold (Bank 2)
2015 Nissan-Datsun Truck Pathfinder 4WD V6-3.5L (VQ35DE)

So, this code can mean the catalyst material has broken apart in the bank 2 catalytic converter and is sometimes blocking the outlet. I suggest removing the unit to look down inside with a flashlight for inspection. Bank 2 is on the driver's side of the engine. Here is how to remove and install the exhaust manifold and catalytic converter. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.
