This is an old post, so I'm sorry to bump it, but I'm having the same issue and in case others search this I want them to know it's something other folks are dealing with.
My D3 will reboot at random while cleaning, and occasionally while on the charging base (I'll hear the start up noise). Sometimes the reboot will happen 30 seconds after start, sometimes as long as 2 minutes.
What happens is that the D3 will stop, sometimes leaving the vacuum active and sometimes not. After about 30 seconds of it sitting stationary the start up noise plays. During the entire process the green light stays solid, it never falters. As far as I can tell the battery pack connection is firmly seated.
I have yet to get a complete cleaning run of a single room.
Unfortunately it needs to go back... simply does not work, hopefully defective and a replacement will work better.
