Engine Cooling problem
1995 Chevy Trailblazer 6 cyl Four Wheel Drive Automatic

I have a 95 Trailblazer, when it reaches about 185 degrees or so it will start running rough and die, in order to get it to start again the engine needs to cool compleatly down-we've tried going through the fuel system, but nothing helped. Any ideas on what might be causing this?

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
