Overheating with A/C on / e-fan issues

Last week I turned on the A/C and a short time later the dash light came on and I saw I was overheating (almost pegged out). I switched the heat on and continued home. Temp went down drastically. Later, I tried the a/c again to see if it was just a fluke. Same result. Overheated. Got home and the coolant in the overflow reservoir was bubbling. Very hot.

Yesterday I popped the hood and turned on the jeep. Turned on the a/c and low and behold the drivers side fan (e-fan) came on immediately. WOOHOO I thought my previous troubles were a fluke.
NOPE. A few minutes down the road, and she overheats again. I park, pop the hood, and the drivers side fan (e-fan) is no longer running. I go home, turn the jeep off, pop the hood, turn the jeep on again, and then try the a/c. No luck on the the drivers side fan coming on.

I let it sit for a few hours. I try again. Pop hood. Turn on jeep. Turn on A/C. and the fan immediately turns on . I notice the fan may seem a little slow, possibly a little wobbling (not erratic). I watch it for a few minutes and I notice the fan slow down a bit, then goes slightly faster. But ultimately a few minutes later the fan turns off entirely. Thats where I left it, and began my search on the forum, but yet to see anything on this particular issue.

My jeep is a 1998. 4.0 4x4 Classic (I noticed years matter how the cooling system works)

So the overall question is what's yawls thoughts / opinions?

All the posts I've read are simply about the fan(s) not working period ... or not shutting off when the jeep is off.
This situations seems different in that it starts off working (possibly slow though), and then turns off.
Also, when the a/c is on its blowing cold and I do hear the clutch engaging intermittently, and the fan on the passenger side is spinning.

Thanks as always for the the future / potential help and comments.

I"m also now wondering if this is just a side issue, and there is a more serious issue going on other than the e-fan not working properly. Something to do with the a/c maybe?
