John Deere 6400 just quit running

[John Boy 68]

I was loading hay in hayfield and got out for a minute to move ramps. Tractor was idling and all of sudden cut off. Motor turns over but is not getting fuel to injector pump. Cannot hear the tank pump running. I have checked all fuses and relays in fuse boxes. When I try to start I hear a noise like something arcing under the dash. Is there a relay under the dash I’m missing? Thanks for any help just don’t want to have to carry to JD shop.

I don’t know if there is a relay under the dash or not. I know if I heard arcing I would be finding out what that was immediately! No way I would want my tractor on fire in the middle of a hay field.

My first guess would be a ground lug came loose and the “arcing” sound you are hearing is a loose ground wire.
