04 S10 Blazer quit running

[65chevysub]

First time posting here and need some advise please. We have an 04 S10 Blazer, 4.3, and today it quit running. First the gas gauge, and tach quit, then no lights(DRL's turn, etc.) Started running rough, then quit. I tried to start it, but it just clicked. Jump started it with my 65 Suburban, and ran for about 2 minutes then died, and no start again. Just clicks. Replaced the starter about a month ago. Towed it with my truck, to the local auto electric shop, and he says it might be the power distribution module. It's been running fine since we bought it about 2 months ago. Anyone else have this happen, and what was the cause/repair?
I'm not up to speed with these new vehicles that's why I drive an old Sub. so any help or ideas would be greatly appreciated.
Thanks
Paul
