The problem is electrical. It could be the coil or coils or some ignition
module. What is happening is as you drive air curculates under the hood
removing some of the heat but once you stop the heat accumulates under the
hood causing the failure until it cools down some. Find the problem now or
it will start to fail even with a little heat.
