Looking to buy a jd 301 A that has a good engine but when you let out on clutch engine dies due to something locked up in the rear end or power drive. Anybody seen this problem or can help?

Sounds like your transmission is shifted into two gears at the same time along the lines Tx Jim suggests.
Removing the top cover is usually the only solution. In this way you can re align everything and also look for broken parts.
Sometimes the wear of the parts plus shifting when there is pressure on the gears as often occurs using a loader, causes one gear to slip back into position just as you are selecting another.
A dragging clutch can exacerbate this happening.

That's what I suspected. I was hoping the repairs could be made without splitting the tractor. I don't recall one shifter being easier than the other, just remember they shifted freely. The tractor is on a farm 5 hours away and I wanted to research a little before I make the drive to bring it home. Thank you both for your knowledge!

Maybe the set screw in a shifter fork became loose. One could inspect shift forks by removing rockshaft housing.

The left shift lever on my 2030 sometimes will "pop" up and allow two gears at once (the cover is worn and the snap ring will not stay put).
I can usually lift and reinsert the lever and get it to shift correctly, but sometimes it is so bound up I have to jack up a rear tire to release the internal pressure on the gears.
So see if the left lever will pull out. If so that's where the problem is.

I finally made it home with the JD 301A and checked the gear shift mechanism and all looks free and shifting freely. I have also removed the rock shaft housing and all gears are moving freely. I'm wondering if maybe the Main hyd pump may be locked up causing the problem? Feed back is appreciated!

If frt hyd pump was the problem engine wouldn't run with traction clutch engaged or disengaged. More than likely trans has one gear engaged all the time which could be a gear galled to a trans shaft when gear should actually rotate on shaft.

I cannot imagine a situation where a hydraulic pump could resist an engine's power without a shaft just shearing off.
I remain with the gear box being the problem.
If it is working now then adjust the clutch and continue to use it until it happens again.
Then carefully remove the rocker shaft cover and as you do so be observant for the tractor suddenly being free as if in neutral.
Sometimes just the removing of the shifter/rocker cover will allow the gears to free themselves.

Maybe seized brakes that are now free?
