Chevy lumina shutting off randomly

[BlitzCB7]

Like it says, the chevy lumina shuts down randomly and from what I was told it normally happens when something is messed with like the heater, stereo, and oddly enough when the brake pedal is pressed down sometimes. I'm stumped so does anybody have any answers?

It seems like there is something wrong with the electrical system. Maybe there is a short in the system that causes it to shut off when the heater and stereo are messed with or the brakes.

I'm thinking that it is a short but what kind of short should I look for that will affect the car the way it does?

maybe check the ground to the batt or oher stuff you took out to fix something? just take a look at the things you did to the car if radio,batt ect...

It's a friends car so no previous work done by me. It's been raining lately so I'm just trying to get a gameplan before I go check it out and see if I could help them out
