Why did electric fans stop working?

Does the engine reach normal operating? How hot does the engine get in degrees F? The low speed may not come on till about 220 degrees F. The fans may come on, if you turn on the ac, under the proper conditions.
Check for applicable trouble codes, to check codes, yourself, at the least, you need an obd2 code reader. Some of the national brand auto stores will check codes for free, if there are any. Also, check coolant temp sensor. Don't replace anything unless your testing points in the direction. Check applicable fuses.
I'd check codes, first.

My 96 jeep grand cherokee keeps dieing when it gets hot

My first question would be, do you know if the cooling fan is coming on ? ?
The computer can shut down the engine if it reaches 250 or 260 degrees. You could also have a coil or other electrical part that is failing when hot.

Low Temperature

250 is not low, it is just about to boil over, coolant boils at 260 in a closed system, water boils at 120.Your car should not exceed 200, 220 max. Or just 100 degrees over the outside temp, like 87 degrees out, your car should be running at 187. Until you stop at a light and it idles for a minute, then it will climb.

Coolent fans dont tun on

Check the fuse and relay for power. The fans come on when the engine reaches 220 degrees or when the ac reaches 200psi.
Is the check engine light on ? It should store a trouble code.

Yesterday our 2002 safari started cold and within 2 miles the tempature went to 250 degrees. We stopped and let it cool for 2 hours, again the temp went up within a mile. I replaced the thermostat but it...

Could be one of two things, maybe both, either the water pump isn't doing it's job right, or the radiator is clogged. In either case, it should be replaced.
