Prints ending early

Hi all,

I upgraded the firmware on my 2014 Sunhokey Prusa i3 to Marlin 1.1.0 yesterday. PLA prints work even better than before - no problems at all. However, when printing with ABS, everything goes well until about 20 minutes into the print when my i3 either 1) suddenly stopps completely and turns off the heaters or 2) stops, turns of the heaters and moves the print carriage to the upper right-hand corner of the build-plate and gives a "Finished." message on the LCD screen.

Because this only happens when I print with ABS, I figure it must somehow be related to temperature readings, so I tried disabling both the "THERMAL_PROTECTION_HOTENDS" and "THERMAL_PROTECTION_BED" options in the firmware - to no avail.

This has me completely stumped, so I was wondering if anybody out there had an idea as to how to fix this issue. I've attached my Configuration.h and Configuration_adv.h files for reference.

I should also note that I have tried printing with both a Repetier Host local server and directly from a SD card.

Update: The last attempt stopped during the 1st layer and simply stopped and shut-off the heaters, here's the repetier server log:

The SD Init Fail leads me to believe your controller is restarting.

Maybe power supply isn't powerful enough to to power everything, like the board, heaters, motors, fans, and lcd.
You might try unplugging the lcd from the control board and print from repetier to see if it gets any further
