Can you post some log entries (dmesg, syslog, pve logs etc.) 5 minutes before and after an reboot?
Let u know which hardware you use and how do you configured them.
Which load and how many VMs do you have?
Do you have some metrics from your monitoring?
Could you update PVE and the FW of your servers?
Do you use HA functionality from PVE?

I have 12 vm on this node (all linux) and 38 vm for all my node

I have a ceph cluster on 6 others server to store my vm

My 4 nodes are in a proxmox cluster so I guess corosync in on and i think wathdog too (but my vm are not configure to use HA)

I have put file with post for load and log

My hardware for my hypervisor

It looks your Nodes have public IPs, is it possible to put then behind a firewall? Eventually you get a "magic packet" which forced your application / server to crash or do you get an DDoS attack. Is your password secure? Eventually your password is hacked and someone do some bad thinks on your nodes.

What about your network, do you have your own VLAN for external and internal Communications or do you share this VLAN with many other Dedicated Server Customers? Do you have shared NIC for different service types?

Could you please upload more log files? They are many other interesting log files which can help us to see what's going on.

If you not use the HA function, have you tried to turn watchdog off and see if the problems is persistent?

Is there anything running before the node fails, like backup, cronjob, unattended updates or something else?
It depends on the system you are using, you should take a look at your server / Mainboard manual. Normally it is an BIOS option.
I have turn watch in the bios but after 4 day one of my node decide to reboot still nothing in the log
It seem to me other people have kind of erratic problem in the forum but noone seem to have the clue

I do not really believe in DDOS because I have nothing in my monitoring indicate that

So still on it

An DDoS Attack should not be have multiple GBit bandwidth, in depends on the system and configuration. So often 1Mbit can be enough, it depends on the attack itself. There are multiple ways to do that.

What about all my other question?
