Dan,
Sounds like a short somewhere in the speaker cables, binding posts, or speaker(s) themselves. Check the binding posts. Sometimes if you over-torque them with spades, they can break or turn enough to have the wire inside your speaker touch a metal part (or other wire) causing a short. Just a hunch. Also inspect speaker cable terminations and connection points for broken solder joints, etc
If the amp stays on without a speaker load, it probably is not the culprit (no need to take the cover off). If you have another set of speakers, hook them up with existing cable. If it shuts down, the problem is in the cable. If you have another set of speaker cables, hook them up to existing speakers. If the amp shuts down, the problem is probably the speakers internal wiring, or binding posts.
Good luck.
