Car just shuts off,, no warning.

[Burnt 1]

I am currently working on my friends car, and it shuts off at any ramdom time., but dies no matter what your doing, you start the car, it will run, then just dies like you turned it off, no spittin or spuddering, Just dies, it will start right back up, sometimes it will run for 5 min, 20 min,, or 1 min, then same thing... BUT when the car shuts off, one of the relays on the drivers side, right up on the firewall, ( 4 of them) you can here it clicking, What are they for.. o yeah its a 95 avenger

thanks
