Makerbot Replicator 2 Stops Printing

I just picked up an older Makerbot Replicator 2 and my first print with it went just fine, zero issues. Moving to a new print, I've had a problem with the machine stopping mid-print (printing from SD card). It will print the first layer no problem and stop about 3/4 of the way through the second layer (11% of the overall print). It doesn't stop extruding, it just stops moving. The firmware is 7.4 (tried updating but says trouble with conveyor when trying).

Anyone have any ideas why this could be stopping mid-print?

Did you try re-slicing?

I did...changed the orientation of the object and resliced. Same results.
