This may seem silly, but have you checked your water level? Check it at the radiator when cold, not just at the plastic coolant recovery tank. Could be the thermostat also: check my article http://econofix.com/thermost.html
The electric cooling fan may not be operating, or the fan clutch may be bad (if it has a standard belt driven fan) althouygh these problems will usually show up in traffic and be fine going down the road

If the radiator is more than 8 years old, it's probably clogged.
If anybody has worked on it lately, one of the most common screwups is to leave the spring out of the bottom radiator hose, causing it to collapse when it gets hot. It's not likely the thermostat, but you can take it out for a while just to check. Or just put a new one in for $6.
Also make sure your radiator cap isn't bad and not letting the cooling system pressure up.

First of all, be sure you haven't picked up some paper or plastic that has sucked up onto the Radiator or the A/C condensor.
It could be a thermostat that is sticking and not opening all the way, therefore restricting the water floww through the Radiator.

plugged radiator. reason: the faster you go the less water it can move and cool down, but also check for any debris in front of the radiator or the thermostat but after 7 years in the radiator business ive seen this before. i have also seen water pumps that the impeller has started to grind down because of the dirty coolant and it cant move enough water. do this start the engine until the vehicle is at normal operating temp, dont get it smoking hot, just normal temp. turn it off and run your hand down the radiator, if it gets cold towards the bottom you have found your problem

You need to have your radiator flushed out and refilled with new water and antifreeze.
Check the oil and see if it looks like chocolate milk, a sure sign that you have a leak in probably your head
gasket.
Possible water pump failure on its way...
Feel all of your water hoses and see if they feel like
nice, good rubber. Are any of them stiff and cracked?
Maybe you have a water leak. You can tell if this is the
case when you open the radiator cap to flush out the radiator. If the level is low, that is a sure sign you are
loosing water somewhere. Check for leaks in hoses.
Hope this helps,

Probably a bad thermostat. The faster your motor is revolving, the more heat it creates, hence, why it was cooling off when you slowed down. It shouldn't do that though. Take it to a shop.
