Jim, hard starting after hot is caused by gas ---we have winter blend gas in our area, starts the end of september and goes untill around the begining of april ---- after restart would run rough for about a 1/4 mile then fine, cool fuel to the carb - all fine untill the next stop
I had/have the same gauge problem only with winter gas, during the summer fuel pressure reads fine even on the hottest days - I believe the gas line is getting just hot enough for the fuel to turn to gas (bubble) causing inaccurate readings especially at idle for a few min. mine would drop to about 1 psi drive for a couple mile and check gauge and fine 6-7psi ---------

Hard start after hot, fuel is boiling out (easier vaporization at lower temp of the winter blend)
Adding race gas 2-3 gal per tank($$$) seems to stop the hard starts or turn off the electric fuel pump about 30 sec before stopping motor(hard to get into the habit to do this) or just remeber the car is flooded for hot restarts untill spring

Oh, generally only a problem on carberated cars Fuel injected usally no problem --fuel pressure 6-9psi carb to 30+psi injected
