Have you set IdleAction= and IdleActionSec= in /etc/systemd/logind.conf?

If not, this looks like the suspend request is triggered externally and
logind simply executes the action.

Do you have a tool like xfce4-power-manager, mate-power-manager,
lxqt-powermanagement etc installed?

Does systemd-inhibit list anything?

Can you run dbus-monitor --system (as root) and check if you get any
dbus messages for org.freedesktop.login1 at the time the suspend happens.
