Electrical ?? On 1991 Chevy blazer s-10

My fiance went shopping with the kids yesterday and the blazer stalled out on her in the bank parking lot ...

She got it restarted... and then like 30 seconds later it stalled again.. and had no electrical power to anything...(Headlights, doom light and hood dome light work)

She walked over to the mall and finished shopping .
I met up with her an hour later and put jumper cables on it and tried to start it..
Nothing..
Triple A came and towed it to the house...

We pulled the battery off and took it to Autozone.. It tested good.

Came back home and reinstalled the battery and tightened it all up and it restarted.
Just for kicks I shut it down . And was able to restart the blazer 3 more times. This 3rd time I let it run for about 30 seconds and then it just died again..
No Electrical power to any components. (Except for headlights and hood light and interior dome light)
We have disconnected the battery several more times and reconnected it..
But cannot get a restart...
As of now..
We have headlights. Interior dome light and under hood light..
So we cant start it... No power locks/ brakes/windows or dash lights..

I noticed something else.. That the Dash indicator are stalled in there last position when it was running. 1/2 tank gas shows and Oil pressure is stuck in the middle too..

Any help or suggestions would be appreciated.

It's Fixed......!!!!!!!
Yup...

It was A red Power cable on the firewall.. It had 2 cables that ran to a fuseable link..
We ran a jumper cable hot @ the firewall to the red cable on D/s before it goes to the fusebox...

Thank Lord.. For the quick .. free fix..
