My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.My info is somewhat limited on your model here but I had seen no one else has responded and would like to see if I can help here.If at any time you feel that I cannot help with this please let me know.

This sounds like a loss of power causing this fault here and may be caused by an issue with a loose or corroded or even damaged battery cable needing cleaned and tightened or replaced.I would check the power and ground feeds from the battery as well as the power feeds at the starter,alternator and fuse panels for any issues.If any issues are found they will need to be repaired to correct this fault here.If these are checked and found to be o.k. let me know.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
