Model 1N1L15V.
When lifting a heavy pallet and traveling, going into 2nd stage the pump slows drastically. Basically anytime you press the accelerator in 2nd staging it slows. If you stop lifting, take your foot off the accelerator, the pump speeds right back up. I have tried to change the settings in the dashboard but got nowhere. Any ideas/thoughts on this?

what Swoop asks about is my 'most likely cause' too, (best w.a.g., without a complete model and serial number, among other things)
but,,,
you should know that the manufacturer and OSHA all say the operators must be trained and know -not- to lift or lower while travelling, as it changes the center of gravity (more so with "a heavy pallet") in a manner that is 'less than as safe as possible", so actually watching the battery voltage AND travelling and lifting would not be the recommended manner to check the diagnosis, nor to operate the truck. I would suggest that you can stall the lift at full up for less than 3 seconds, and watch the battery voltage and get a much better idea and be 'more safe'. you will first want to read what the "at rest" voltage is, then compare it to the 'after 3 seconds hydraulic stall' voltage.
whats happening with battery voltage when this occurs?
sounds like the battery is dropping too low under power and is taking away power from hydraulics to run traction.
