I have an 861 ford tractor. It runs great for about 15 to 29 min, then stops running. When it stops it acts like its out of gas.I check the sediment bowl and it's full of gas. I opened the bolt on the bottom of the carburetor and gas comes out. I tried running it with the gas cap off and and it still stops. I tried running it with the air cleaner off and it stops running in 3 min. Can anyone help me figure out why this is happing ?

Do some simple trouble shooting.
go out and run it till it dies.
Check spark as soon as it dies and make sure you have a good blue/white spark that will jump a 1/4 inch gap or more
#2 pull the carb drain plug and make sure you have a good steady flow that will fill a pint jar in less then 3 minutes and 2 is even better. And yes catch the gas to make sure it does not have water/dirt etc. in it.

The one he is asking about has the sediment bowl by way of a banjo bolt at the carb so no screen filter at the carb.

Another thing you may have is an incorrect fuel or not having it routed as it should and the gas if boiling in the fuel line

Maybe not the gas, could easy be the coil is bad.
Starts and runs, once the engine gets hot stops.
Restarts later no problem, is typical for a weak coil

Exhaust intake gasket leak .While running at idle, spray short burst of ether at gasket in various areas . An increase in RPM would indicate gasket failure.CM

When you took the drain out of the bottom of the carb you tested for presence of gas, now you need to check for flow as old described. I have experienced a coil failure as Bruce described. It is very difficult to verify, but it can be narrowed down by checking for spark IMMEDIATELY after stopping as old described.

I was also going to suggest a bad coil.

I suggest replacing the coil also. I had that happen to me 35 years ago about drove me nuts until in desperation I changed the coil. In the years since I have come across 3 or 4 people that had the same problem.
