I have a 2017 mx4800hst and when I raise or lower the FEL it puts a load on the engine and the engine dies, every time.... the engine will start right up until I raise or lower the FEL again the engine will die??????

Any ides on what should I check?

Also I'm in California and it was 70 degrees today so it's not cold....

Thank you Todd

I am thinking fuel .....clogged filter(s)
restriction of fuel line.....
Fuel cap?

as 85 mentioned. easy test.... remove fuel cap and see if it acts the same. report back.

also is it an instant die or like a die of overload?

If I raise or lower the loader it will put a strain on the engine until it dies... if I rotate the bucket up or down its fine, only when I raise or lower the loader..... my mx4800 has a BH92 backhoe on it and the dealer just added 2 rear remotes.. you think that has something to do with it?

IF dealer JUST did something to it - have them check it back out.....that few hours, something is amiss!

Could still be fuel - but sounds like something else now.

Sounds like the dealer has two lines crossed, but before calling the dealer be sure all the disconnects are seated fully. Just unplug them and then reinsert.
