Default Random shut down on Paranoid android 4.0

A few times a day, my Verizon G2 running PA would turn off and require me to hold the power button for more than 8 seconds to turn it back on. Other have said it's due to the processor going to a very low speed when the phone is not being used, which is when it turns off. It almost never turns off while I'm using it. Is there a solution to this problem that many others are having as well?
