Host is transmitting and unreachable

I have had a NAS on my network with a DHCP static mapping for 2 years, a month ago it went offline and I mapped the other NIC to the static mapping and got it working again. Yesterday the NAS went offline and most of my attempts have failed after 30 minutes or so.
I have set the NAS to be a static IP and removed the DHCP static mapping, this lasted for a few hours and then failed.
Rebooting the NAS will result in 30 minutes or so of connectivity before I can no longer reach the web interface or any of the containers.But if I do a packet capture I can see that the NAS is communicating to other devices on the network.
What seems to be happening is that if I put the NAS on a different VLAN, I can do a static mapping and have it work, but not on the network I currently have it on. I can see that in the ARP table it says incomplete (despite having a static DHCP mapping and creating an ARP entry). I can delete the incomplete entry, but nothing seems to work.
How can I get this to work without rebuilding the VLAN and firewall rules?
Thanks!

@illeatthat Just a guess, when it drops off is there anything using that IP? Disconnect it and see if you can ping the IP.

@steveits
When it drops off I can no longer ping. I disconnect it and it continues to no longer ping.Last night I changed to regular old DHCP on VLAN 12 (the VLAN where the NAS is supposed to be), it dropped off after 30 minutes or so.
This morning I changed it to regular old DHCP on VLAN 10, it has been going for 2 hours.

Interesting update.
I put a workstation onto VLAN 12 to watch what is happening.
After 30 minutes it seems to "drop" off the network, but it actually looks like it is dropping the gateway. The workstation I put onto VLAN 12 can still reach the NAS and obviously ping it.Using pfsense's "ping" tool, I can try to ping the NAS from the source address of the VLAN and it results in 100% loss. So pfsense can't see it.
