Is it shutting itself down when running from battery?
Try running from USB and see whether you have the same problem there.

Whenever you run into what you believe is a hardware problem, can you  
add that incident to
http://wiki.openmoko.org/wiki/Prototypes
Erin had a similar shutdown problem (see #15 on the wiki page), Matt  
is currently looking into it.
Can you get in touch with Matt/Erin to find out whether you have the  
same problem or a different one?
