While driving all my dash lights came on (brake, all doors open, check engine lights), My RPM nd MPH started fluctuating then both dropped to zero. Car still on but when pushed gas pedal to go car would barely go forward and then it **** off. I turned on a few hours later nd turned on. All light on dash still on but rpm and mph back to normal. Car was fine for like 10 miles nd it did the same thing. Left it like an hour and turned it on again nd made it home. Now it'll turn on but won't stay on. Husband tested to see if any problems but reader didn't detect anything.

 

Get the alternator tested. Also check battery connections, et.

 

Also test the main relay while you're at it.
