Check your plug wire boots on the plug end. They have a tendency to separate above the metal sleeve. Check your coil pack for cracks. These can open and short out when heated. Vacuum line to the fuel pressure reg. from the intake. Just changed the motor in one two days ago, and I had all of these problems. Also just check the water pump when you can cause the impeller can separate from the pump shaft and overheat the motor without warning. Just remove the thermostat when its cooled down and see if you can move the impeller with your fingers. If it even wiggles a small amount replace it. I got left on the side of the road because of this. Just thought I would throw that in there because it really sucks if it does happen.
