Suspect number one is the device overheating. The shutdown is triggered by the EC. I don't know how you can enable ACPI debug output on BSD though. On linux, it would be "echo 1 > /sys/module/acpi/parameters/aml_debug_output", so whatever the FreeBSD equivalent of that is. If you can see lines like "EC: LID OPEN" in wherever the system log is, then you know that's working. Look for things like "EC: THERMAL OVERLOAD" or "EC: THERMAL SHUTDOWN" in said system log, right after a shutdown.
