The car will be running fine and then the temp will shoot up and the car will overheat with no notice. At that point it will stall and won't restart. When it cools down and fluid is added it will start. There are no signs of leaks under the car. Have replaced thermostat and hoses are fine. The car will no retain the fluids.

it sounds like a water pump not circulating antifreeze properly
SOURCE: I have a 94 nissan altima that overheats. I
sounds like where the water pump meets the engine has warped or the gasket has been blown. Since the water pump has to come out anyway to fix it then i would suggest replacing the pump. It is 30 to 40 more.

Are you sure there is not a air pocket in the engine after changing water pump,
there is only 1 thermostat
Testimonial: "thought of that already, but this all started before the replacement. thermostat checked out ok and replaced it and pump. water isn't circulating."

i actually had this problem on my 97 sentra, its the air idle control valve. when your car is idling with your foot off the pedal, the throttle plate is closed, so this little valve opens up to allow air to detour around the closed throttle plate so your car can continue to run, when you give it gas the plate opens so your engine can increase revs.
after awhile the idle air control valve gets dirty with carbon buildup and eventually makes the valve stick so no air can pass through it which is why the car will stall when it attempts to idle. all it needs is a good clean. its very easy to do, just get some brake cleaner and a toothpick or q-tip or some other small brush.
locating this valve is a bit tricky, yours is a 2000 model mines a 97 so it wont be in the same location as mine, but what your looking for is a little cylinder type thing somewhere near the intake with an electrical connector at the back of it, take the connector off, mine had 2 phillips head screws holding the valve in place, once removed the valve slides out, and you can proceed to clean it. make sure you get all the black soot out of it and play around with it until it opens smooth, reinstall and it should run fine. to find out the exact location of your idle air control valve id google it or try a nissan forum, but itll be close to your intake manifold near the firewall. best of luck, once found its a very easy fix.

i have a 2005 1.8 nissan sentra.i rplaced the radiator becuause it was leaking.so when i did i took it for a test drive and the needle went to hot then back down to middle ways between the C & H BACK IN FORTH.so i replaced the thermostat. now as far as i can tell it is staying in the middle of C & H. i can't feel no water though cerulating through the top or bottom hose of the radiator. so now that i told you what i done so far my question is???? ( my heater is not working in the car it is blowing out cold air & i left the car runnng for about 45 min. even took it up and down the road.still cold air.what do you think i need to do?????????? )
