Question: wondering why it's bogging; stalling and shuting down while driving then turning back on?

Trying to help a friend find out whats up with her car.
It was originally her fathers. then it was given to her. she kind put some "ware and tare" on it since she's have had it. Now, it seems to just want to die on her. She NEEDS this vehicle to run! it's really all she's got right now.
There have been a few times now that when she starts it up it just doesn't want to. When we do finally get it to run, it bogs out.
What really weirds us out, is when I am driving down the road and all the lights turn off and the car shuts it's self off COMPLETELY! Then a few seconds later turns back on!
What's the deal?! Please help us!!!

Check the terminals and connections at the battery. Sometimes greenish/gray corrosion gets on the battery cables and when a new battery is installed, it doesn't make a good connection. Use a little sand paper or terminal brush to clean them up. It may be all you need to do. If they're OK, you may have to take it in and have it checked.

When battery voltage gets low, all sorts of strange things happen, including multiple dash lights illuminating.

If that's good, have the charging system tested. It sound like it is an electrical issue.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
