In the early 80s they incorporated a shutoff solenoid in the event of overheating. What happens is when the engine reaches a critical level it then opens a vacuum solenoid forcing the engine to stall to prevent it causing extreme damage. I am not sure its location on your vehicle but when it happens again, try clamping off some vacuum lines on the solenoids to find out which one clamped will the car start. hope this takes care of things. ps...change your fuel filter, It may be restricting your fuel.

Good Day,
Sounds like the thermostat is working properly, the only other cause for the valve/lifter noise could be the oil pump is not pumping enough oil up to the top of the motor. I suggest doing an oil change(if you haven'y aleready), be sure to flush several quarts through, after sitting for 5 years I'm sure the old oil is pretty sludgy, this well help rule out this possibilty. As far as the water pump goes, It either works or doesn't typically when they are on there way out the will leak from the gaskets. A bad head gasket would cause white smoke form the exhaust as coolant get's into the oil and is burned off, so I don;t hink this is the problem.
Here's a start for you, hope this helps and good luck

does the fan come on when supposed to? you could hook your fans to a toggle switch and run them manually from start to finish this may help. also did you bleed the system after replacing these parts and purge all air from cooling system? is the coolant coming out of the resovoir hose?

there are 2 things id check first. the coolant temp sensor. and then the map sensor. good luck

I had same problem in varius trucks and motorhomes with the same engine size (460)and this is caused by excesive heat from the engine in all 460's,when hot if I stoped at a gas station to fill,once I tryed to start it again it felt like the battery was almost dead and bearly turned the engine over.what I did was that I added an after market engine oil cooler and that fixed the problem.
The overheating of the car can be due to many
reasons and you need to check on each one to confirm the working of the system.
1. In the first place the working of the engine must be assessed. it must be
smooth with a good indication that the tuning timing and the power seems good.
This will confirm that the settings of the engine is good and so there is less
scope that the engine seems to heat up on its own.
2. Secondly the radiator pressure cap must be tight and good, the radiator MUST
not loose coolant after a run or in a few days time- since this must be a
sealed system and there is no scope of water overflow or loss unless there is a
leak- sometimes the leak is too microscopic as under high pressure only steam
might escape and so reduce the coolant. So check for leaks while the engine is
hot , specially the radiator, the hose
or the fittings.
3. The working of the water pump must be good to ensure a good flow and
circulation, so check for leak in the water pump, check for presence of water
in the exhaust or leaking on the engine gaskets.
4.Make sure that the coolant is good and clean if not drain and refill , if
there is presence of rust please have a good flushing of the radiator or else
the chances are that the radiator ports can be blocked and reduce the
efficiency of the cooling .
5. Finally the cooling fan, the radiator fan must be working, check the
thermostat/thermistor to work accordingly with good flow, have a good water jet
wash on the radiator for a clean radiator cooling fin exposure.
