Wow, really strange! My VZW HTC-TP2 started doing it on Friday, May 20th, 2011.
The screen would go off as normal after a couple of minutes, however, when pushing the "Screen-Button" on the upper left nothing would happen. When a call came in the screen would finally come on and I ahd a chance to operate the phone, but as soon it went dark it was froze again. The only way was doing a reset via the hidden button or taking the battery out. Then it would work for a while. I uninstalled some apps I thought may be corrupted, I even tried a different storage card. Nothing helped.
I had my data on backup via MS-Myphone, so I decided to reflash the phone using the latest VZW_MR3 release with WinMo6.5 and Manila 2.5. The only issue I had afterwards, VZW couldn't verify the phone when I tried placing a call. Eventhough VZW had my EID on file and they saw my phone in the Network it wouldn't receive a 26-digit identification code that you get when doing the *228-Programming. They guided me through the hidden ##778-Menu and I had to enter it manually.
Now I reinstalled all my apps and synced files and contacts, since Sunday afternoon I had no issues at all.
More or less, if you get that "sleeping death", all what you can do is reflashing you phone!
