hey everyone, i have a 2006 charger r/t, it recently started acting up, when driving it wants to shut it self off, rpm's go down,but then it picks up power again, it shut off at a light,when i turned the key it cranked back up,it has been doing it while i drive, it losses power no lights go on in the dash, then picks up again. Any information of what it might be or what i should be looking for is greatly appreciated.
