Lift runs for a while then when it gets hot it just dies,

I have seen two codes pop up, a 522752-2 and a 522752-4. When these codes come up it backfires some, when the -4 code comes up it dies. Any ideas I'm stumped, please help

I am having exactly the same issue as the OP and would like to find a solution. Where could i find wiring diagrams to trace this out ?

well before you get ahead of yourself, think about your initial description of the problem "Lift runs for a while then when it gets hot it just dies"

is it running hot?
make sure its not a heat related problem with overheating first.
an overheating truck will shut down if it hits stage 2 overheat.
(generally you will have overheat codes though)
have you checked the fault history to see if there are any?

otherwise i'd go with what kevin suggested.
a faulty connection or ground or maybe it could be a relay or ecm related problem showing when it warms up.

Thank you very much! With the way it was acting that's what I was thinking but wasn't sure.

522752-2 is loss of crank pulse.....522752-4 is loss of cam pulse...li would check to make sure wiring and connections are good at sensors...also check relays and fuses for issues...sounds like a wiring issue at some place....either a ground wire or a connector issue...

The first practical visible-spectrum LEDs were red, not white. The red colour was the easiest to produce using the semiconductor materials available at the time (the 1960s). The alloy gallium arsenide phosphide (GaAsP) used emitted red light.
