Oh yes.

Try getting it to run from the command line with a blank
environment with 'env -', e.g.,

  % env - run_stuff.sh

Typically a crontab job runs with a much reduced environment.

Alternatively, stick a printenv in your crontab to see
what environment it is working with and compare to your
interactive environment.

You might also find crontab's sister command, 'at', helpful
to get tighter feedback cycles.
