06 Charger problem?

The wife was headed home today and as she was making the right turn onto our road (45 deg), the car shut down. Lights were on and of course the power steering was stiff as there was no power. She pulled to the side of the road and put the car in park and turned the key off then started the car back up with no other issues. Any ideas guys? Sounds like some sort of breaker off then on. The oil light came on which is normal when things shut down. She services this car regularly and she is virtually the only driver. I'll check the oil level in the morning but that will be ok i know. It's a 5.7 hemi. Any ideas? I dont need her loosing confidence in her car. It's to costly to make her confident in something.
