Marlin FW restarts randomly during print

I like the simplicity of this script, but it isn't usable for me. The printer simply restarts at a random point during the print. I tried enabling Marlin debug prints, but it only repeated the commands it received, nothing useful.

Here is my output:

I editted the script like this to set the baudrate for the serial port:

     export DEVICE=$2
     export PIPE=/tmp/print3d-$(date +%N)

+    stty -F /dev/ttyUSB0 115200
+
     echo "[INFO] - $(date +%Y-%m-%d_%H:%M:%S) - Preparing to print $DATA"
     mkfifo $PIPE
     cat $DEVICE > $PIPE &

To be sure this isn't a FW bug, I tried updating to latest (basically master) version of Marlin, didn't help. I also tried using Repetier Server to confirm this can work and all my test prints succeed when using that.

Any ideas what could be the problem? Repetier Server does a few tests to find out which serial communication mode to use during the setup. Maybe that's what's missing? See step 2 in https://www.repetier-server.com/manuals/1.4/index.html.

EDIT: As you recommended on a reddit post, I also tried stty with raw -echo. Didn't help.
