Paul,
A few things come to mind.
1. Electric fuel pump is bad and stops when it gets hot.
The next time you stop dead leave your key on and listen for the noise
of the fuel pump.
2. Crap in Carburator bowl that plugs up a main jet every once in a
while. Rebuild carb and put an inline filter close to the carb.
3. Leak in carb at accelator pump or power valve. Causing too rich
a mixture and flooding you out. Does it blow black smoke when you
restart? If so do carb rebuild.
4. Broken/loose wire in distributor.
5. Bad Condensor.
6. Bad wire connection between igition switch and fuel pump.
7. Bad ground on fuel pump.
8. Primary ignition wire(s) shorting out or loose.
9. Bad coil ( already replaced you said) see item 8.
10. Ignition resistor open will allow the motor to fire only
when you are cranking the motor. The motor will die as
soon as you let off the starter. The starting circuit bypasses
the ignition resistor. (Already replaced you said) see item 8.
11.Crap in fuel tank preventing fuel from getting to pump.
12. Smashed steel fuel line under Tiger or old flexable hoses
that are plugged.
13. Bad vacuum leak in intake or carb/mount. Check vacuum
lines too. Including the power brake booster. (However this
would cause problems when cold more than when hot)
14. Vapor lock is unlikely ( boiling of fuel so fuel pump can't
work) as that normally only happens on mechnical pumps attached to
the motor, not on a rear mounted electric pump.
15. Clogged inlet filter in carb ( if so equipped).
Recommend you disconnect the fuel line at the carb and
then provide a catch can for fuel. Turn on ignition and you should have
a good stream of gas flowing out of the fuel line into the catch can.
Be very careful and have a fire extengisher near by.
Do not do this over a hot motor or inside your garage!
