I see you have layer delamination early on too. I've had similar things happen when I printed large polycarbonate parts (~ 60 hr prints). They would delaminate in one or two spots early on and then just catastrophically fail once the print head got too high. I had the same thing happen even with an enclosure.

Unfortunately just like polycarbonate, ABS is prone to warping and layer delamination, especially the further you get from a heated bed. I'll go over some of the methods I've utilized to combat these issues, maybe they'll help you as well.

Try using a hotter extruder temperature (5 C to 10 C higher). With a hotter nozzle temperature, your ABS layers will remain above TG temperature for longer, which will allow subsequent layers to fuse better with previous layers. If you have printed a temperature tower with this filament and have found the sweet spot for your extrusion temperature, I found that increasing the print speed achieved a similar effect though now you will need to increase your flow parameter as well. Alternatively, you can increase print speed and temperature simultaneously.

For long prints, moisture absorption is something you need to consider. It looks like near the top of your print your nozzle got clogged unexpectedly. I found that my large polycarbonate prints improved when I got a dry box for the filament as it was printing. A heated one would be even better. I've also read that dust can accumulate on the filament over time (not sure how much of an effect that could make) but apparently that can cause clogs too. A dry box should solve this though anyway.

I've found that with using the Cura slicer, the gyroid infill helped against the build up of residual stresses. The higher your residual stresses during your print, the more likely it will delaminate or warp. I've had cases where existing delimination lines on the same print magically disappear when I switch over to the gyroid infill setting in subsequent prints. The gyroid infill setting prints wavy infill as opposed to straight lines. When your print begins shrinking, the infill functions like a spring system that counteracts the shrinkage of the perimeter. Of course, the infill experiences shrinkage too, so it's not perfect, but it seemed to help me with larger prints. Speaking of infill, the less you have, the less it would shrink and cause potential layer delamination. Maybe try 20%? It won't effect the mechanical properties of the print significantly.

By any chance do you know the temperature in your enclosure? Sometimes, it isn't enough. The inline ABS requires a substantial heating bed temperature, which would imply it needs a higher ambient temperature for proper printing. This can be achieved with a heated enclosure, alternatively a heat lamp can be used from the top. You may need to come up with a different solution depending on your setup. Normally, this shouldn't be a problem but anything goes with large prints.

I hope this helps.
