If the electric fuel pump is mounted higher than the fuel tank it will have problems getting suction. Be sure that it is mounted down on the frame rail (below the fly wheel is a good spot) so that the suction side is always submerged. Otherwise the pump will take awile to supply gas to the carb bowl. It may get it eventually, but it will burn itself up trying.

I have a 1989 Sears Craftsman 20 HP garden tractor with an Onan engine. It will run for a few minutes and then just stalls out like it is not getting any gas. I wait a couple of minutes and it will start...

Try this:
The next time it begins to stall, loosen the gas cap.
If the engine runs smoothly, you have to clear the vent holes in the fuel cap.

Deere 318 with Onan B43G won't start w/ starter engaged, but if the engine "catches" when I turn off igniton, it runs fine. I can only get it to start by pulsing the starter on and off--only starts when...

318's are known to have flywheel problems and poor engagement of the starter due to incorrect alignment of the starter to the ring gear.To check either of these things you need to take the motor out of the tractor to look at the ring gear,starter drive and starter aliggnment.Before you go through this pain replace the ignition switch or have it tested.p.s deere only supplies a replacement flywheel but a ring gear can be ordered through a case dealer if you get it for a stinner with the onan engine.

Sears 19 hp twin 42 inch tractor, won't start if hot

Two things come to mind. First it could be not getting enough fuel when hot due to carb adjustment being too lean. That could be that the float level in the carb is set too low or the low speed jet is set too lean. When cold the choke circuit in the carb supplies the extra fuel required.
Second in some enjines that have low compression they start cold but when hot the compression drops below 60 psi and makes starting very difficult until engine cools down.
I suspect a fuel problem.
