I need help!

I have posted and threaded with little to no responses. on a Kobelco sk300lc mark iv I am having the engine stall out and die . checked the single pump solenoid, and replaced . Is it surpo0se to buzz or click when 24 volts is added. I have power to solenoid and it is new . If I extend any function all the way or stall out hyd s it will kill engine or bogg it down. In d mode it will dig at idle no problem till cylinder rod hits the end of its stroke. then it will stall out engine . Not sure...
