Low power and no high speed travel

My lift recently started having issues. It's has very little power when moving both forwards and backwards and with the platform lowered it will not go into high speed travel/2nd gear, whatever it may be called. The batteries are pretty new so I'm sure that's not the issue. It also worth noting that other functions such as steering, platform raise and platform extension seem 100% with no sign of reduced power. Any ideas would be greatly appreciated.
