My first thought would be a bad or low voltage battery. Chrysler vehicles love to light up when the voltage is low. Do you have a code reader? If not, head to an AutoZone or Advance, they should read it for free. If they get a code, check back here before buying anything. You could have them load test the battery and check the charging circuit while you are there as well. Good luck.

2004, likely the solenoid pack and/or the valve body causing the limp home mode. Have the codes read after the battery is changed.
