Mower Deck Blades Disengage

I have a Deere Z737 with 444 hours. The blades stopped turning today as I was mowing. The engine runs fine and the mower handles well. When I engage the blades they turn for 15-30 seconds and then stop turning. It does not affect the engine and I can still drive it. Suggestions?
 
I would check the PTO electrical for a resistance above 1.7 ohms or a current draw under 7 amps (3-5 amps normal draw). Any resistance below 1.7 or current draw above 7 amps then the clutch is partially shorted. A partial short will damage the wiring, switches, and relay.
 
Thanks for the suggestions. I found a guy who wanted to buy it and got a good price so sold it and bought a Z920M. I'd had it 19 years and so was ready for another one.
