Vent clogged in the carb? It needs atmospheric pressure on the bowl.
I don’t believe it’s fuel related. As spark disappears after warm or hot

A common problem with tar-packed coils is they warm up and internally short much more frequently than oil-packed ignition coils (wow, now you know I'm old school if I know that, smile).

That said, this thing doesn't have a pickup coil or electronic ignition, does it? They too can work fine when room temperature but then have an open when hot and fail.

I tested the coil with meter both cold and hot and had same readings. Coil was actually cold to touch when it shut down.

Is there a "low oil" shutdown on this?

You should look. If the sensor fails, it could/does cut off the ignition.
I don’t see an oil sensor on the wiring diagram. Only an oil light.

If it has a warning light, there has to be a sensor/switch. Find it on the motor and unplug (or maybe "short it" if it's got two wires). This will eliminate that possibility...

Well I checked all grounds, switches, relays and safety’s. All check out. I replaced the plugs and the distributor and seems to run great again. We shall see. Thanks
