76 280 power will just shutdown randomly. Anything time, any speed. I have to turn it over 5 or 10 times before it fires up. Once it does it runs great until the next time. Could be 10 mi or 100.

Temperature not an issue. No exhaust or fuel issues.

When does it lose all power, when braking or stopped? or below certain rpm?

Could be the ignition module. More details about before, during and after the shutdown would help. Tachometer behavior, is it a dead stop shutdown or are there a few sputters? Automatic or manual? Etc.

I agree with ignition module. Heat kills them over time.

You can verify by watching the tach the next time it fails. If the needle falls faster than the engine revs die when coasting then it is an ignition problem.

For a fix, I recommend this rather than buying a new module: http://atlanticz.ca/zclub/techtips/distributor/index.html

It shuts down while driving. Braking/stopping does ok.

Precisely what my Goon was doing.It was the solder joints.

Do you have a caps on the battery neg/Pos terminals I had the same problem ended up checking every major electrical component in ignition circuit and it was the battery shorting out the car when the hood would make contact with the battery

He hasn't been here in almost two months.........In your case; you either had the wrong battery or you battery wasn't properly secured.
