You shouldn't need to push the filament by hand. But kudos for sticking it out for 3 years.
If your machine is 3 years old, have you taken apart the hotend assembly at any point? Sometimes buildup occurs between the nozzle and brass tube or peek part and causes excess friction which would cause the constant under extrusions.
I found that after about 1.5 years on my UMO, enough gunk had built up on the interior of my brass tube that I would have to lower my speed to compensate for the extra friction and then as you describe it would fail a few minutes into each print.
I changed out the brass tube, block and nozzle and everything is all good again. (I was lucky to have ordered an extra hot end pack)

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
