Thanks for the input. I guess I'll have to consider the TPS, also. I
do have some info to add, though. I flushed the cooling system and
replaced the thermostat. That cleared up the problem with the
temperature gauge fluctuating, and the cutting-out symptoms also
stopped. Now that it is Spring Time, the weather is warming up, and
the cutting-out symptom is returning. As long as the weather is
relatively cool, it doesn't appear, but if the weather temperature
reaches 70 to 75 degrees Fahrenheit (or higher) the symptom returns.
It appears to be definitely heat related, but I don't have any idea
what the heat could be affecting. It doesn't seem like it would affect
the TPS... am I wrong about this?
