First what comes to mind is some sort of program incompatibility.
Please answer the following few questions:
1. Do you have the latest version of the OS? It should be 2.1 version S:i500.04.EA28. If not, try to perform a system update.
2. If you have the latest version of the OS. Did the phone started to restart after after you downloaded any program?
3. If you answered yes to question 2, try to perform a hard reset and reinstall one program every few hours (no sooner then a frequency a reset that you are experience).
4. If resets still occurs after all of the actions above are done, contact Verizon and ask for replacement.
My guess is that your phone is freezing, not turning off. This is probably why you need to pull the battery for your phone to work again. Doing this too often can force your phone to open in safe mode which limits functionality but will allow you to remove applications (such as the last one or few that you've downloaded).
One thing I have noticed as I download more and more apps is that several apps open up in the background for various reasons. Since these apps don't close unless your phone requires memory, when your phone suddenly requires heavy processor use, it may freeze.
What worked for me was using Advanced Task Killer (it controls what stays open), and I have it set up so that it force quits things at a safe level (so none of the important programs get turned off). Also, it is set up so that it closes apps only if I'm not actively using the phone. This has significantly cut down on the number of times my phone has frozen on me.
But it's definitely better to find the root cause of the problem and not just treat the symptoms. You should determine if an incompatible application (as papaleo mentioned) or too many applications running simultaneously or even something else.
Please try the suggestions provided by the very helpful members papa leo and 10sEn. I am also sending you a private
message for added consideration. If you need further assistance, please reply back to my private message
with your name, mobile number and a call back number.

Thanks to the community members for your input. JenNavarro, power cycling is definitely an issues that could frustrate you and prevent you from using your phone as much as you want so I understand. I researched your issue and found some steps that may assist you with resolving the power cycling. I would first put the phone in to safe mode. This is a great step to determine whether a 3rd party application is the cause of an Operating System / Application issue. After you have enabled and disabled this functionality to take off any third party apps that may be causing the issue, power cycle your device. If this doesn't work, the last step would be to perform a master/factory reset. I will list the steps below for safe mode and for the master reset.
Steps to put phone into safe mode:
1. Power down the device.
2. Power the device on.
3. When the Verizon Logo is displayed in the power up sequence, press and hold the MENU key.
If successful, SAFE MODE will be displayed in the lower left corner of the screen.
(To deactivate Safe Mode, power down and power on the device normally.)
Steps to master reset the phone: Performing a hard reset will remove ALL data including the Google account, system data, application data, application settings, and downloaded applications.
