If this is for REAL, and the engine dies when the electric clutch is energized, even by a spare battery, it would have to be that the magnetic field from the clutch coil is somehow stopping the electronic ignition from triggering.
Hey, let's confirm that by using a spark tester to verify that spark actually fails! (Also, does this have a electromagnetic fuel shutoff solenoid on the carb that may somehow affected?)
One other though, I think theses engines have ball bearings on the crankshaft, but is it possible there's crankshaft endplay that's affected by the clutch being energized that somehow messes up triggering of the ignition?
That being said, I have read MANY posts on the 'net where a Predator has been installed in a DEERE garden tractor, seems to be a VERY popular repower, and from those reports, they work well.
So what's going on, perhaps ignition system is not quite right/marginal and quits sparking to easily from an external magnetic influence?
I would check "air gap" between flywheel magnets and coil, perhaps a little less or a little more might make a difference?
As I understand you, you have tried powering the clutch coil by a totally separate spare battery.
If that is the case, and you are connecting direct to the clutch coil without ANY tractor wiring involved, just for giggles try reversing the polarity of the power to the clutch coil, battery (-) to the clutch coil lead and battery (+) to the chassis.
This will make the clutch "pull in" but produce a magnetic field of the opposite polarity. Does that affect the engine "dying"?

Today's Featured Article - Product Review: Black Tire Paint - by Staff. I have been fortunate in that two of my tractors have had rear tires that were in great shape when I bought the tractor. My model "H" even had the old style fronts with plenty of tread. My "L" fronts were mismatched Sears Guardsman snow tires, which I promptly tossed. Well, although these tires were in good shape as far as tread was concerned, they looked real sad. All were flat, but new tubes fixed that. In addition to years and years of scuffing and fading, they had paint splattered on
