My 93 Miata had similar symptoms and it did turn out to be a bad Thermostat.

Replying to: yogi56 (Aug 26, 2009 8:43 am) If you are getting leakage at the drain plug, perhaps your system is over pressurizing? If that is the case, it points to a bad radiator cap, as any overflow should be using the overflow bottle rather than leaking out elsewhere. I am trying to remember where the temp sending unit is located, but I cannot recall precisely. I keep thinking of the oil pressure sending unit, which is on the top, front, and dead-center of the engine. *sigh* Darn memory.   If the car is actually overheating, how long does it take for this to happen? If the thermostat itself is bad, the overheat situation will happen very soon after starting the car (essentially, it will "warm up" and then quickly overheat). If it is a matter of the fans not running, the temp will continue to slowly climb once it reaches operating temperature, but the increase will be slow. For the fans, you need to isolate whether it is a fuse, relay, the fan motor(s), or a sensor controlling the circuit. It is helpful to have wiring diagrams (usually included with a Haynes manual and, I would think, Chilton) so you know what is connected. If you look up the name of the sensors in the book, it should point you to the location of them in their respective (inspect/service) areas.
