I also believe its rom related.
I've had my phone go into standby mode when on the charger, and miss my alarms, calls, and txt msg.
I've had it go into standby mode, while the phone sat on my desk.
I've done the hard reset and the soft reset, and it seems to help for a few days, and then it starts happening again.
HTC tech support, says its a known issue and are working on an update for this. While The telus data support department also says its a known issue and to bring it to the store where it was purchase, and see if they can fix it, or have it exchanged. I go into the store, they do a soft reset, and call my phone while in standyby and it wakes up for the next couple of days.
