I'm sure it's unrelated but you need to look into a better power supply. Looking at your log from when the printer was running your voltage is dropping all the way down to 11.1 so I can see that causing issues.
I would lower your extruder acceleration quite a bit...10000 is rather high, especially for a non-geared extruder which I'm assuming you have due to the low steps/mm on the extruder. I would also raise the instantaneous speed change on the extruder to something between 800-1500.
I just wondering if that real high acceleration on the extruder is causing the issue.
