Sounds like a fuel delivery issue, it could be a plugged puckup screen too in the fuel tank, i'm not sure what the setup is on a NH machine though. One way to check is to hook up a bottle of fuel and connect direct to the lift pump to eliminate the fuel lines to the tank. If it runs strong you know the problem is further back the line.

cb, read through the "632 Shutdown" post as it has several "places to start" for similar symptoms. Good luck.

Which engine does it have? There was a Perkins 4-108, and a Kubota and maybe a gasser. Mine had the Perkins. The lift pump was mechanical and ran off the engine. It would get hot if the engine was hot. Check the engine oil and see if it's too full and/or smells like fuel--if the lift pump is bad it could pump fuel into the engine.

Also, a blocked vent on the fuel filler cap will cause a vacuum preventing fuel delivery. Try removing the cap and runn it full open and see what happens--if it runs replace or clean the cap.
Another thing--if it's running too hot it will lose power too.

Thanks for everyone's help. It was the electric lift pump. Replaced and running great!
