Stall under load

Hi all I have a Hyster S2.50XL around 2005-2010 I think, running on gas.
She's stalling whenever the hydraulic controls are maxed out, whether it be steering, tilt, side shift or lift it just stalls.
Looks like there is a system on the Hydraulic pump that is linked to the carburetor to increase the idle. How does this work and what usually goes wrong with this?
Hoping to get some info before going through a repair shop as they are all flat out and booked out for 3 weeks or more.
Thanks
Paul Mac

I would suggest you check pressures on the hydraulic pump if all functions are causing it to stall. Is engine idle speed correct? If it is to low, the engine will stall. Because it is a gas engine, check the timing also.

Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
