I have a similar problem with my 1995 blazer. I find that wiggling the relays in the glove compartment starts mine up again. So far I have yet to figure out how to permantently fix this.
The Chevrolet Blazer cooling system diagram can be obtained from most Chevrolet dealerships. The cooling system diagram can also be found at most auto-parts stores.

The 2004 Chevrolet blazer 4.3 liter engine cooling system has a capacity of 4.7 gallons. The cooling system should contain a minimum of 50 percent antifreeze.
Describe the problems you are having.
I would suspect a faulty fuel pump or fuel pump relay.
It has 1 coolant sensor, 1 temperature sensor
Overheating. Have the cooling system checked.

Hi, Head gasket is leaking, allowing oil to enter cooling system. Peace, crigby
If you mean coolant temperature sensor.... ITs on the driver side, behind the alternator. Must remove the alternator!
You could have the start of a head gasket that is leaking. I suggest that you have a shop to add leak detector to the cooling system and check it with a black light.
