Grand national over heats and won't start

[Vencill66]

Went on the freeway today and it slowly started over heating so I pulled over, the temp was around 210 it wouldn't start until it was below 200. Does anybody have any ideals on what could be wrong? Thanks

How many miles are on the car?

What mods have been done to the car?

What temperature thermosat is in the car?

When was the cooling system last serviced?

Is the cooling system full? What coolant is being used?

Do you know if your fan is working? Was it on when the car was overheating?

Have you ever had to replace a head gasket?

210 isn't horrible (not good, but not horrible). I wonder if the fuel pump is weak and you are getting really low pressure in the rails when it heats up?

I'd check the fuel pressure and start back tracking from there.
