The bit about sometimes if you can get it to run long long enough it will then stay running sounds just like the problems I had with a 391 in a Ford C750. The first time the truck was started for the day the temp gauge would go up, into the hot area and you could hear the coolant start to boil in the engine and push into the bottom of the radiator. If you shut it off for a couple of minutes and then restarted it the temperature would drop back to normal and would stay there all day unless the engine were allowed to cool off. I changed thermostats several times and it made no difference until I switched brand of thermostat.
The problem turned out to be the thermostat in the cab over application was moved a little forward of the intake manifold where there was not circulation past it on the engine side. Since there was no circulation past the thermostat as the engine warmed up the coolant in the heads would get hot enough to boil before the coolant near the thermostat was warm enough to open the thermostat. Shutting the engine off for a couple of minutes when it got hot allowed enough time for the temperature of the coolant to rise at the thermostat so that it opened. Once it opened up and had circulation through it, there was no longer a problem until it closed completely. When I switched brand of thermostat I ended up installing one that had a bypass hole in it. That allowed some circulation past it when it was cold and open at the proper time.
