HP DL360, VMware ESXI 6.5.0 Reboots when passing though GPU

Hi
I have an issue with my HP DL360 G8 and VMware ESXi 6.5.0 update 1,
I have tried pass-though GPU (Nvidia Quadro) also i have tried a AMD Radeon with the same results.
While the VM is off it’s fine, but soon as it try and boot the VM, the server just restarts. No Purple screen and no error logs.

I’m at a loss why, but i have seen other people have had a similar issue but haven’t seen a solution to fix this. Some say move back to 5.5 but there are still issues there from what i have read.

Any help would be good.
