You are not the only one. Ive met a good many of Saturn owners (most were 2001 L300 drivers) but they were plagued with the problem you have and practically identical codes. The following remedies have been known to work:
1. Replacement Battery Cable
2.Replacement ECU Wiring Harness
3. Replacement of ECU

That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.
You can go to most auto parts stores and they will pull the codes for you for free.

If your lucky, your car is still under warranty. If your warranty is over, you can go to Auto Zone and have the car scanned for the DTC codes. The DTC codes will inform you the issues that need to be addressed so you can have your car running 100% again. Note: Auto Zone scan free of charge and can give you the step by step instruction to address the issues free of charge and if there are any parts that need to be replace, there parts price are reasonable and most of the time are life time replacements. Good luck and keep me posted, be glad to help you get your car running 100% again soon
