If you want to start troubleshooting and start from the least expensive check your pto switch...If that is testing positive move down to the connection that veers off to the clutch and test that, if that is operating properly and you are getting power down there you might need a clutch....I have the same mower and recently had to replace the clutch because I was experiencing the same issue, so I went from the least expensive item and the problem was actually the most expensive item..
I may not have read your post properly though...now that I have re-read it I realize that you say your engine is turning off when you pull the PTO....Do the blades attempt to engage before the engine dies??? If that is the case then I agree with the safety switch suggestion...
