Most common cause IS that the battery does not have enough power/charge.
If a fuse blew, it wouldn't even click (if you have a fuse)
If that isn't the case, then check your wires, gears, motor, piston, etc... If there is something wrong, you'll probably notice something strange immediately.
You're JG is shooting 430 fps, even an 8.4v nimh mini can power that. I don't see why it has to ONLY take 11.1v lipos... So it isn't a power issue.
