mendel stopping mid print

hi I have tweak skeinforge to generate gcode that prints nicely but now my mendel (techzone monolithic electronics) stops at about layer 3 repsnapper still says it has a few hours of print time remaining but it just stops dead any thoughts?

after trying a few things I notice the last line when it falls over is "received start" don't know if this helps

It means the firmware has crashed, reset, and it telling the computer its ready to receive gcode. Is there any pattern in the last gcode before it crashes?

yes it is always in the same spot line 414 of my 20mm test cube

well I ran it again to get the log file to copy here and this is where it stopped

the funny think is when I KICKED it the log file showed a few more lines dont know if it relivent

17:26:26 Send >>Receivederial Error: LineNr is not the last lineNr+1
17:26:26 Send >>Received:Resend:0 with parameter 0

and this time it didn't give a "received: start"
