I have a 1/2 hp motor just newly installed that after running for a bit just stops. This is a new motor and replaces a new motor with the same problem. Ask question so I can answer. Patrick
Could be thermal overload tripping. Can you post pictures of the wiring set-up ??? Is it 110v or 220v ???
If two new motors doing the same thing, has to be in the wiring or the worst luck.
Check your incoming voltage (with motor running if possible). If it's low, that will increase motor current and cause the thermals to trip.
Some motors have auto resetting thermals, some have a reset button.
Low voltage can be from too small of incoming wire, loose connection, corrosion, wire run too long for size, or a combination thereof.
Geezs why didn't I look at the diagram. I read his reply on talking to graingers and figured it must be right Dah moment on my part .Ck your switch , loose or burnt contacts . Wire to small for current draw , has to be a brake or loose connection. Take the old motor and mount a plug and plug it in on another circuit if it runs ok I'd say you better get an electrician to Ck the one your using.
