need some help

[natext6]

I went to work today, and then when I went to go home, the car wouldn't start. It coughed and sputtered, and then after about 20 minutes, it started. I started driving home, assuming it had been a battery issue. Then, after about 10 minutes of driving, the engine cut out, and I had to pull to the side of the road. I tried boosting it, but it didn't help. Also, my emergency brake either isn't disengaging, or the light isn't turning off.....don't know if this is related. Anyway, does this sound like anything you guys have heard of?

 

The car is a ft4wd xt6
