HTC TP CDMA Freezes... reboot takes back to pre-configured ROM state

[grocerylist]

I tried searching the forums but didn't exactly know what to search for. I have a HTC TP and have tried multiple ROMs for the past several months.

Recently with the 6.5.1 ROMs I have noticed that the phone at some point will become unstable and locks up. This could be cause by any numerous programs. Specifically today it locked up on M$FT's My Phone during the SYNC. The only way for me to get the phone unlocked is to take the battery out. After I put the battery back in the phone boots but I lose all my previous settings (configured email accounts, phone contacts, etc). It's like the phone hard reset itself and took me back to the moment immediately after I flashed the phone with a new ROM.

Has anyone had this problem? It's really frustrating going through this process a few times a day and restoring from a backup, just because the phone locks up.

Any help/suggestions are much appreciated!

Thanks
