Tractor wont start hot

[ot2o]

My Branson 2810 runs great, all the gauges and sensors are appear to work properly, no lights or indicators. However after I run it for about 30 minutes it refuses to start until I let it sit for about 30-40 minutes. When I turn the ignition it just turns over and over with no sign of it even trying to start running.

I thought it could be my temperature sensor because it was faulty. I replaced it however this had no effect aside from making my temperature gauge work again.

Anyone experience this before or have any tips?

Thanks

Fuel shutoff solenoid failing hot causing a no fuel issue.

I had the same problem and couldn't figure it out. Eventually the fuel pump failed and my dealer told me to save some money and install an aftermarket electric diesel fuel pump. Ever since them, I haven't had any issues with not being able to start after running it for awhile.

Like Eddie said buy an aftermarket one, I bought a spare one off Ebay for a fraction of the price

Three other possibilities, if the fuel pump isn't the issue:

On both my old Mustang and my even older Cub Cadet, the ignition coil would flake out when hot. Some hairline crack in the internal wiring would open up when warm, and then shrink back closed when cold. Very frustrating problem to find, as both would randomly die while in use, and then a little later fire right back up and run fine.

The Kawasaki V-twin on my Deere Ztrak 757 has a habit of boiling fuel in the carb bowl, when shut down after a long mowing session. After refueling and firing it back up, it runs rough for that first half minute, until enough fresh (cool) fuel is swept thru the carb float bowl to get it below the boiling point.

I've had many other small engines, nearly all 2-stroke, with clogged fuel tank vents cause a failure to restart when hot. Always easy to debug by just loosening and retightening the fuel cap, to balance pressure in the tank.

I have had a starter cause this but you could tell it just did not spin quite fast enough as when hot.
Having said that I also suspect the fuel pump as going bad.

Appreciate all the responses. How would you recommend I test the fuel pump? Wait until I am having the issue and disconnect an output hose to see if I am getting fuel?

When you turn the key on it should vibrate, that's what mine does...
Or pull the hose off the end and see if it squirts fuel when you turn the key

Is that a Shibaura motor or similar ? Those I'm familiar with (In Ford & NH machines) need glow plugs even for a hot start.

My old Fiat had a problem with hot starting. I think it was solid tappets adjusted too tight. So, a little heat and everything was running loose and it wouldn't start.

I can't say if any modern tractors would have the same problem
