I was driving my xfire on the freeway the other day for about 25 min and as I was exiting the off ramp my car dies! I let it sit for 5 min then it turned back on. Then a couple days later I'm driving for about 20 min pull into a driveway and car dies... I turn it on 5 min later..... The very last time was 2 days ago; I drove for about 15 min parked the car at the store came back and car doed not turn on, it doesn't even crank, no clicking sound, nothing! This time car sat for 2 hrs and still didn't turn on. We eventually push started the car... Is the RCM issue?? Car won't turn on anymore.....
