Code P0441

Commonly that code indicates a failing purge solenoid. If it is intermittent as yours the solenoid is going to fail soon, and engine vibration is bouncing enough that it is unbinding not long after setting the code. The same thing happens if you tap them with a tool, suddenly they work again, only to fail a week later.
It's an easy part to replace, one electrical connection, two hose clamps and the mounting clip.

Hello,

Code P0441 Evaporative Emission Control System Incorrect Purge Flow

This code can get triggered due to a faulty vapor pressure sensor, any leak in the EVAP system, issue with the circuit of the sensor, fuel tank overfill valve cracked or damaged etc.

It is possible that the issue is minor and that is why the light is intermittent.
