Definitely check wiring and all switches, starting from the ignition switch, behind the panel.
Occasionally over the past year my John Deere Sabre would be difficult to start, and more recently every time I would fully engage the PTO lever for the mower deck, the engine would die.
$500 in parts and labor later (carb, plugs, fuel pump, fuel filter, battery) I discovered that the wiring harness/plug behind the key on/off switch was loose.
When bumped slightly by the PTO lever engaged, it would loosen and engine would not restart until the loose switch/plug settled back into place temporarily.
Another sign that it was loose wiring or a switch should have been that sometimes the engine would die while rattling around over a bump, even without the PTO lever engaged.

Cleaned everything up around pullys, checked belts and and put all back together only to started it and hear a very high pitched circular squeel in the motor. I'm thinking the motor is going bad. Thanks for all your suggestions. But i'm thinking it's time to take to a pro.

It may be a bad spindle bearing that is seizing up when you engage it which puts too much load on the engine and makes it die. You may hear some squealing sounds from the spindle and the belt may smoke. Most all these spindles can be taken apart and you can easily replace the bearings. I replace mine every couple of years. Get them by sets of 10 on Ebay really cheap. Make sure you leave the spindle on the deck when you remove the spindle shaft because often the brittle aged attachment bolts will snap off if you try to remove them. They are very hard to drill out. You can leave the blade on the bottom of the shaft after taking the big top bolt off. Then put a new bearing over the shaft bottom and then add the spacer sleeves and push the shaft through from the bottom. Put top bearing on tighten nut. On some Craftsmen like the Troybuilt TB 30 MTD equivalent they have a safety switch around the deck shoot and if that is not positioned right or goes bad the engine will die when the blades are engaged.

It could also be a bad battery. One bad cell is enough to not let the fuel solenoid work properly when the mower blades are engaged.
