I am picking up a new test light to time it statically tonight. I know for a 
fact the timing is off now. I switched out the dizzys on the Buses last night 
and had to remove the clamp on both. I heard a few small back fires before I 
gave up for the night.

Knowing the history, timing will cause the engine to turn slowly or not at all 
as the combustion happens while the piston is still travelling upwards. Setting 
the timing properly could very well cure the starting problem. Any time points 
are set, replaced, or carb adjusted, the timing should be checked and adjusted 
accordingly. It may take care of the stalling as well. Not sure if I can swing 
by this afternoon, but I might be able to.

It's possible but the carb has only 400 miles on it. I am thinking fuel pump 
but I suppose it's possible.  Problem is I can't get it started to really check 
the fuel pump

Sounds like a possible stuck needle valve not allowing the fuel bowl to fill up 
as you drive, since it conks out after 5 minutes or so. then refires.
Is it a 30/31PICT Carb? There pretty straightforward to mess with. 
I'm thinking that or fuel pressure issues.
I will say the BEST diagnostic tool to have is a fuel pressure tester to check 
the fuel pump pressure bteween pump and carb inlet.  Just about any fuel pump 
you get 'new' today is pushing way past 3lbs...
Needs to be between 2 to 3lbs,no more or you'll blow fuel past the needle valve 
and truly have hard start issues with fuel being forced all over the place.
Any FLAP can order one, just run a tee in it and plug it in between pump and 
carb.
 
I'm gonna bet fuel pressure might be your issue, but get a carb rebuild kit, 
cheap and easy to do as well.
Sounds like your ignition systemhas all been worked over well.
Now one thing I have seen before, its crazy, but a coil can get super hot and 
cause issues to after a brief period of running. Have you swapped out coils? 
Just another idea...Make sure you get the coil with the internal resistor as 
well.
 
best of luck.
