Daikin fan coil unit

Good day Sir!
Please, there is this Daikin ceiling conceal fan coil unit that run for about 5-10mins after which that unit will stop. Both the indoor and outdoor will stop.
Unit will not run until a reset button on the outdoor is press and runs 5-10mins again and stop.
The unit has been flushed and recharge but the problem persist.
Could any one help with what the problem might be?
Thanks!

Can you post the full model numbers for the indoor and outdoor units and any fault codes that come up on the controller?
