Fluid level is OK? This sounds like air in the system and a failed accumulator. When you start up, a weak accumulator has to fill which is likely the cause of your light at start-up. The accumulator bleeds down over time when the car sits. That fluid is returned to the reservoir so if you check the level then it will look full. Start the car and give it that 30 seconds before you check.

Air can get in if you have very low fluid which could be the case if your accumulator empties into the reservoir and then when it fills, your fluid level falls below the pickup for the pump. Or your fluid is just simply low.

You could also have a weak pump which would explain the return of steering assist when you increase RPMs. But it could also just be pushing the air through.
