522xi - Starts 2sec then stalls

[Fordiesel69 272]

I was not operating it, but in the middle of a mow it shut off like someone turned the key.  Once we towed it back, it just starts and within 2 sec dies.  If I hold the key in the start position, magically it still runs.  

 

Seat switch is good as I have parking brake fully set.  I jumped the switch just to be sure.  Oil level is at F.  Not sure how to check further.

I don't know if all model years are the same or not.

Will guess at this one. Download the file and in it is a diagram for just the ignition. Easy to follow.

Likely electrical and since it runs while being held in start (much to the dismay of the starter motor, I’m sure) I’d suspect the switch itself may be giving intermittent on the internal contact with the “I” terminal while in the Run position but being OK when in the Start position. 

I’d begin by voltage checking the wiring starting at the “I” (ignition) terminal on the switch. It should have 12v when the key is in Run or Start positions--and be sure to wiggle the key while it’s in the Run position to see if that affects anything! I’d also carry the voltmeter around and once it stalls out, immediately (without touching ANYTHING ELSE) check for voltage at the “+” terminal on the coil. No voltage there means no spark and gives you a starting place to find out why!

Make sure your red wire is hooked up the carb anti backfire solenoid and you can hear an audible click when turning it to the run position.

Does the xi series have a powered ignition?  I thought those had a magneto?
