B7510 won't start after it warmed up

[Hessmonster]

My B7510 starts fine when its cold but won't restart after its been running for a bit. After its sits for a while it will start again. Any thoughts?

Will it run well for a long time if you don’t turn it off?
Do you use glow plugs when you’re trying to start it warm?

Yes it runs fine until I turn it off. and I use the glow plugs for about 5 seconds before every start.

Is the engine turning over when it wont restart?

I think Dave is asking and I'll ask, will it crank when warm and not start or not crank at all?

 

[Hessmonster]

Yes it will turn over but not start

And another question...
How long do you have to let it sit before it starts again? 5 minutes or 5 hours or?

I’ve got no good ideas yet unless it is something electronic that is controlling the fuel that goes bad when hot but works when cool. Does it have some automatic shutdown solenoid or do you have to pull a lever to cut it off? If you have the solenoid I would suspect it is going bad. See if you can find a way to test it or remove it to see what happens. Just be sure there is a manual way to shut down the tractor.

I would start by checking the fuel stop solenoid.
It sounds like it's not working when it's hot.

usually let it sit for 45 min to an hour

I'm with Wolfman here....

Stop Solenoids work differently on different tractors..

Some cut fuel off to stop engine, then "reset" to "run" shortly after tractor is shut off. My BX resets to run 10 seconds after tractor shuts off. I can hear the "click" 10 seconds after key-off. It's then ready to go the next time.

Some open when the key is turned on. The solenoid opens wit the key...

I wouldn't throw a solenoid at it before doing some more troubleshooting, like listening for activation or the component's activation.
