Hello , I am new on here so I'm not sure I'm even in the right spot for questions,but hopefully I am. I was driving my 2013 town and country tonight . I was going 55 with the cruise control on and suddenly the RPMs went up to around 4000 and my traction control light came on then followed all other dummy lights. It wasn't getting power . I pulled over **** it off then started it started hesitantly I got about 2 miles down the rd and it just stopped now power at all the fob wouldn't even come out. I went got a different battery and it started up and drove for about 6 miles then repeated same . The new battery is now completely dead also. I just replaced the alternator last yr at this time.

 

Maybe a ground?
