Kristen,
I don't know about there but here the auto parts stores carry some very good Chilton books on older cars and motors that go from very basic to completely rebuilding the engine. That might be a place for you to look for a book that would give you some good and simple guide lines about how things work and also they have pictures of the different parts. They have exploded views of carbs, brake systems, etc. also. And one that came with my 69 cobra has several pages of trouble symptoms in it and a list of what could be the cause. Might be something you could look into when you are browsing the parts stores. Mine don't cover anything with the new electronic systems, but I do have books on the Jacobs Pro street which is what I use. But the basic electronic computer module works mostly the same way, no matter what brand it is. The fact it takes yours that long to cool down enough to start again would almost make me think it has to be something in the electronics.
