You would need to enable debugging in the Development options and download the Android SDK, so you you can get the debugger (DDMS).
Here is another silent issue a few years back on my Eris. And somebody figured out what may have caused it.
Phone is Useless when the Phone Goes Silent Multiple Times a Week
However, you will probably need to know what your looking for (its going to spit out a ton of lines in real time since this is debugging info for the entire OS, apps, etc), and you might need to have the phone plugged in the PC while your on the call. However if it was anything like the individual above, it there might be a looping error that never ends so you could plug it in after you get it (however you still need to be in the call).
And who knows, the Android debugger may provide no useful information.
