Tractor acts like it isn't getting fuel.

I have a kubota mx5100 with a hydrostatic drive. I need a specific part that has to do with telling the tractor to turn the fuel on and it might be the fuel relay or fuel shutoff but I am not sure.

That’s a relay…

kind of looks like this one on messicks, but listed as what I guess is the glow plug relay

Which relay would it be the fuel relay or starter relay? How do I find the part online?
Thanks for the help. I appreciate it. Would the glow plug relay cause the tractor to start and then die 10 or 20 minute later and then not start again for 2 to 4 hrs

I would say no, but I have no idea if the relay I posted is in fact the glow plug relay or how the tractor is wired

I agree this 'sounds' like a fuel-delivery issue.
  • Does your tractor have an electric lift-pump?
  • Is your electric lift-pump running?
    • Key ON... engine not running
    • you should hear it running (klik-klik-klik-klik)

Nope. Not a possibility.

But then, we still need to determine if that is the GP relay or the fuel solenoid relay.

Can you post a pic of where you found it?

The neighbor took it off and said it was the fuel solenoid relay. I wasn't down there my Son was and he is on vacation right now. I just can't seem to find the part online anywhere. I called a Kubota dealer and told them that it was the fuel relay and they ordered the part and had it sent to our house. When we got it today it definately isn't what is in the picture so now I am trying to find the part myself so I can order it.

Without the aid of a MX5100 tech manual I don't know the answer. if the relay for GP that Fordtech mentioned isn't the correct relay then there's 3 of the same relays shown SO 1 of those relay's has a good possibility of being the correct relay

There are 3 T1060-33720 relays used, but the one that @Fordtech86 mentioned was T1060-33710, which is the glow plug relay and seems to look more like the relay in OP's picture. But all this guesswork is unecessary if OP provides a picture of where the relay was located.
