Ariens EZR 1742 Mower Stops When PTO Engaged

The Problem:
When I engage the PTO switch the engine dies.

What I have changed:
I had this mower given to me free from a relative. I rewired the mower due to some of the wires having had a rodent problem. I replaced the key switch and PTO switch. The neutral safety switches where bypassed because they were faulty.

What I know:
I had the mower running after the rewiring and switch replacements.
Now I can start the mower and drive with no issues.
The mower cut grass within the last week.
When sitting on the seat and the key in the on position - When I engage the PTO switch, I can hear the clutch click.
I have tested the seat switch, brake switch, PTO switch, and the key switch with a volt meter and all positions are working at the terminals of all switches, based on the switch guide within the repair manual
I have may have wires in the wrong position
The belt and pulleys turn when manually turning them from the main pulley to the mower deck pulley.
The motor dies quick when the PTO is engaged. There is a little movement on the mower deck but it doesn't seem like it is too stressed to engage.

Any suggestions are appreciated.

If it ran fine for a while after you rewired it then I wonder if the engine can handle a load could be fuel issue when gov opens under load
