I got a Jet JP2000 impact wrench for $60. It's a 3/4 inch drive that's supposed to put out 2000 ft. lbs . I don't currently have an air compressor that will handle it but was wondering if I could get enough time out of it with my 1 hp pancake compressor to loosen a couple nuts given time to build pressure.

The compressor size won’t determine what it can do it will determine how long it can do it. The ability will come from the psi level of the compressor vs the tool requirement. If you already have the tool and compressor give it a go. Won’t hurt anything.

Run the air hose from the compressor to a 5 gallon portable tank close to the work. Then run a short (10 feet) 3/8 or 1/2 inch air line to the impact gun.
The 5 gal reservoir will get off any nut the gun is capable of. Pressure should be as near to 100 psi (or greater) as you can get.

Been there and done that. That extra 5 gallon tank will buy you a couple of seconds at full power. In the cases where I tried that it only worked if the bolts came off fairly easily. After that it will not have enough air to produce 2000 foot pounds. You don't specify what flow rate your compressor is nor the consumption needs of the driver.
Not sure the size of the bolts/nuts the OP wants to remove, but 2 seconds at 2000 foot pounds should break loose everything I need to deal with. Plus, one only has to wait a bit for the aux tank to recharge and try again (and again) if needed...
Compressor puts out about two and a half cfm at 90 psi. The nuts are an inch and eleven sixteenths holding the blades on a brush hog. At least one spline is stripped
Not going to happen with your set up. You'll need a compressor that can supply 90 psi @5.5 to 6 CFM constant. Those guns draw some big air. I went cordless with a I-R 20volt and love it, can take every where and it rocks.
Bucktail,
That compressor will not be able to keep up with the 9 CFM requirements of the impact wrench for more that a couple of seconds. More importantly, if your bush hog is like mine you access the nuts for the blades from the top through an access port provided just for that. If the splined bolt is spinning in the arm no amount of torque will get the nut off. You will have to either come up with a way to stop the spinning or cut the whole bolt off.
I used a breaker bar with an 8 foot cheater to get mine off. Sounds like yours are like mine based on the size of the socket needed.
Good luck and may the orange force be with you.

You need CFM to make larger tools work effectively...including a larger air line feeding the tool. You might be disappointed with the results.
Exactly this. I've yet to see a pancake compressor that has a line coming off the tank that would be sufficient to supply that rattle gun. Forget trying to run it through the regulator, but even directly pipes to the tank with a 3/4" line I don't think you'll get anywhere.

For my use, the electric was also the logical choice. It's only a 1/2" but so far it has handled everything that I have fed it.

That doesn't make you an idiot, it just means that your sockets don't fit !!! 
I have adapters. Enough to use a 1/4” socket on my 1” ratchet hahaThat doesn't make you an idiot, it just means that your sockets don't fit !!!
The plan is to hold the other side with a pipe wrench. Plan B is to cut flats on the head and use a big ass adjustable wrench to hold it. I have a 40 inch breaker bar I can use once the nuts are loose. Could buy a chunk of pipe to use as a cheater.

I talked to a neighbor who has a a 2 hp 30 gallon compressor so we're getting warmer. He also has a cutting torch which can be used to heat the nuts and may be useful for plan c or d.

Yup, and life savers too. I ordered mine when I got the impact wrench.
Matter of fact that is a 3/4" socket in the 1/2" drive here.
I was a mechanic for quite a few year I have tools I rarely use anymore as I mostly just fix my own stuff now. But every once in a while I still pull out the beast of a 1” ratchet I have. It’s gotta weight10-15lbs and it’s older than I am.
