You might want to look at your fuel pressure. Test the pressure cold, turning the key on before starting it and then when it is hot,
You could also have a coil that is not putting out spark when it gets too hot. The engine gets hotter when you shut it down because the water is not being circulated. Once the vehicle is shut down the temp increases for a while. It could also be an ignition modual, sometimes just before total failure they quit working when they get hot.
As you can see there are a lot of things that can cause this and it makes it hard for a repair shop to diagnose with out having it for enough time to duplicate the problem.
If you want to try yourself, you will need at least a fuel pressure Gage.
Hope this helps

Does it do it on both sides?If it is just on one side,a bulb could be the problem.When it does this,check the bulbs,by turning the signal on,and look at the front ,and the back,to see if one bulb is not burning.Replace it .One other problem ,check to see if the turn signal fuse is not blown,but melted in the fuse block.The battery voltage needs to be checked also.Check the charging system.it should be at about13.58 to 14.25.If the charging system is not at least 13.50 at idle,chatge battery at slow charge at 2 amps for 24 hours.If the voltage does not come up above 13.501 at idle,have the alternator replaced.The flashers,and the turn signals require a lot of amps.

There is definately something shorted to power through the brake lamp circuit. If you have any aftermarket equipment installed on your Blazer, I would recommend un-installing it. I have seen similar problems caused by aftermarket alarm systems, remote starters, etc.
I DID do a search for possible Technical Service Bulletins (TSBs) for your vehicle. There are many TSBs published for known problems on your vehicle. However, there are NONE that apply to the symptoms you are describing. If this is not being caused by aftermarket equipment, then some serious electrical diagnostics needs to be performed to find the actual CAUSE of the problem. It could be anything from wires that have rubbed together in the wiring harness to an internal fault in one of the computer modules.
