You may want to see a shrink.
Fuel pumps can have this kind of symptomes when they go bad. Look into the fuel filter and fuel pump. That's the only thing that comes to mind right away. Check ignition as well. When "janet" is acting up, pull a plug or the wire from the coil and see if you see an arc when you crank it over. Don't have a buddy hold it unless you don't like him. Just unplug, leave the plug grounded on the block or coild wire close to the contact on the dizzy and crank. Have your buddy watch for spark.

 

That or maybe an ignition control module, they will do stuff like that.
Usually not on a first start, but once the engine gets hot they overheat.
