Print fail using Cura but OK with another slicer.

The above prints are done on a Balco Touch, from the same STL file. The right was sliced with the latest Cura and the left with Prusa slicer. I have had excellent results with Cura, but does anyone know what I am doing wrong with this. I do not think I have changed any settings. The Touch is set up as a Wanhau printer. All prints start of well, but start to fail about the same level. I have had excellent results with Cura, but does anyone know what I am doing wrong with this.

It looks like the print on the right developed a problem in the hot end.  Those upper layers appear to be severely under-extruded.  The left "wing" on the right model didn't really print at all.

It can never hurt to do some PM on the printer.  Once a month I pull my hot end apart and clean it out, trim the bowden back, check and clean all the trolley wheels and check the X-beam alignment.  The machines run for hour upon hour and do need some attention now and then.

BTW...what material is that?

Looking at the model.. it looks like it starts to fail more and more as retraction would take place..
Possibly check your retraction settings (speed/distance)

Greg, I will give it a clean out but the one on the left was printed just before the one on the right. The material is PLA. BTW, nice bike.

Dustin, thank you for your suggestions. I will have a look at them and see how they compare to the Prusa settings.

"...the left was printed just before..."

Yep, it ran when I parked it.
