Hmm. Hard to say exactly what is going on. It almost sounds like there is something going wrong with reading from the SD-card a bit into the plot file. But this seems strange though since the whole file is parsed before starting the plot (to find min-max coords). Have you tried a different SD-card?
If it is plugged in to a reliable power source that should not be the problem either. When running on batteries you're always at risk of running into low voltage issues where the Arduino would reset.
Cool! Love the clip for holding the pen!
Woho! Well done!
