Could this just be due to all the CPU activity using a lot of power and

No. My Nano battery is weak (those 6 minutes of passes ate 20% of the
battery) but my Sansa battery is very strong still, and it is/was at
full charge.
I don't understand how any of this could repeatably cause a shutdown.
I'm also wondering about why the passes would be faster on the Sansa e200.
Here's a test plugin which does the same memory access pattern, but
doesn't do any cache operations. I wonder if the same shutdown happens
with unaltered.mi4 and this plugin:
http://dl.dropbox.com/u/16662598/Rockbox/pp502x_cache_test/e200_pp502x_cache_notest.zip
If there are any problems then, it's either a bug in the test plugin or
e200 instability under high CPU and/or memory load.
Best regards,
Boris
