My brother's Droid Mini had a similar issue. He checked the weather and put it back in his pocket. After that, it started kind of a bootloop, without booting. What happened was it would vibrate for a second and the screen would turn on, but it was blank. It would stay on for about 5-10 seconds, then turn off for around 15-20 seconds, and repeat. Removing the Sim card didn't help, nor pressing the power button and volume up button (simulating a battery pull). If you pressed the power button to turn on the screen, the led would flash red a few times.
I called a local repair shop and they were adamant that it was water damage. The only problem was it wasn't anywhere near any water and the weather right now is extremely dry. We bought it used and he figured it must've been sold after the water damage, but it's run fine for about 4-5 months. But he wouldn't budge on that being the solution.
So I called Motorola, and the tech had me hold down the power and volume down buttons for 2 minutes, after which the screen appeared that let's you select recovery, factory, etc. But the phone was too low on battery and powered off. So he instructed me to put it on the charger for a few hours and then do a wipe of the partition chache. After it was on the charger for about 15 minutes I heard the startup sound. I did clear the partition cache and it's been running fine ever since.
I don't know if this is the same issue as what the OP is experiencing, but I figured I'd put this here in case anyone else has the same issue.
