make sure battery is good and has been load tested most places do for free. this includes battery terminal ends are clean.then check fuses and finally have a mechanic scan for codes. also, have belt and tension-er checked as recommended replacement is 60,000 miles for both. any oil or antifreeze on belt destroys it.

Hello,

It sounds like you have a battery cable that is going bad. With the key on try moving the cables around to see if you can get it to act up.

Please let us know what happens.

Cheers, Ken
