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
