my TOUCH PRO keeps turning off

[igotmineatross]

ok guys help me out...
i have a sprint htc touch pro the first version i got when it just came out...

i have been running some custom roms on it for a while now...

just recently my touch pro will just randomly turn off when i leave it idle for a while, it probably happens at least once a day. like when i press the power button to check the time or something the screen wont turn on, and i will have to take out the battery and replace it and it will finally turn back on...

but now its gotten even worse, now when i try to turn it back on after replacing the battery it wont even turn on, only when i leave it dead for about 30 mins or so, and replace the battery again it will turn on...

does anyone know what the problem is? or is anyone facing similar problems? the phone works perfectly fine when it is on...

and its not the rom that is the problem because i have switched through a few and the phone still does the same thing...

PLEASE HELP!!!
