Kudos to the mfg who put an "oil sensor" on any AC tractor, or water-cooled for that matter. You have not said if it is oil pressure or oil temp ( perhaps you don't know) . If you're trying to end its days, defeating an engine shutoff feature due to low oil pressure or high oil temp will do it for you.

Scag uses different configs with different machines. The Turf Tiger has an oil pressure sensor and the Tiger cat just has a simple "low oil level" sensor which is nothing more than a float type of switch that sits submerged in the oil in the bottom of the crank case

Oil pressure / oil temp?

Hell it's a the factory sensor it kills the spark if I use too good a grade oil too little or too much. Damn thing just stops dead. I'm assuming that it is the typical single wire sensor that shorts to ground when it wants to kill the engine.

Kohler only uses a single wire sensor in these motors.
Kohler Oil Pressure Switch

"Remove and clean it. When you reassemble put some Teflon tape on and tighten. Should solve the problem. "

HA HA HA HA HA HA HA I can't find it.
I have run my had all around the engine down low where it ought to be. I can't find a wire nor a sensor.
I rather suspect that Scag ordered these engines with little changes from the factory standard that the manual shows. For instance the oil filter is out board. The Oil Drain is on the opposite side of the engine from the manual's location.
I have this image in my head of some Scag engineer deciding that they didn't want some careless hired hand yanking the wire and ruining the motor for the owner because absent the sensor none of them would check the oil, sooooooo they hid it.

If you recognize the mower and know where the sensor is please tell me

SOLVED

I thought it was the oil sensor. But there ain't one. All that time and energy I spent pissing around for a nonexistent sensor.
It was the ignition module - the magneto

Apparently the bloody things fail in degrees and in response to heat from the engine upon which the thing is directly mounted.

So it runs like a top when it was cool and when it got hot it was no fun at the party.

$117 later the mower shop (L & L Clinton NJ) I found it at is a rip off; marks things up wildly, I could have gotten it for half that on the web, had I not needed to cut the lawn RIGHT AWAY, and waited for the postman. Well I solved the problem and won't be buying anything from him again.
And now the mower runs like a top and is out front of my house for sale.

Forget the sting of the rip-next time you'll know. Plus remind yourself of all the things you solved yourself.
