Sounds like a flat battery and the low volts during an attempted start is re-arming the alarm. Regards Peter

Did you find anything that was left on (lights, etc.)? If this has come on suddenly then I would think the battery's on its last legs. Long journeys may charge it up enough between starts, but I wouldn't trust it for short journeys.

If you've got an ammeter check for excessive drain with the ignition off. It could be the diode pack on the alternator.
