Lately I've been having some weird electrical.

Lately I've been having some weird electrical issues w/the car. Somtimes the car is dead & a jump other times it does not.
After pulling out some relays & fuses the car was starting fine until recently I am having starting issues again. The service engine light came on, but went off after driving it for 30 minutes.
Today while driving (5th gear, around 50 mph radio &headlights on) the radio died, the dash died, and the car started sputtering. Like it was going to stall. The service light, the abs light, battery light & Ithe low antifreeze came on the dash. The speedometer, rpm, temp gauge went all to zero.
The odd thing is I heard a clicking sound near the module and fuse box area.
I turned off the headlights and the car ran a little better but it still seemed like it was going to stall.
Once I made it home, I was curious, so I turned on the head light and it stalled. Now it does not turn on. So i'm wondering, what is it?
