What do you mean by "stop"?

Does it shut down or struggles?
If you have an AFR gauge you would be able to know if the pump is not doing ok.
Or you can do some logs with vcds see what's happening

According to the log it could look like the low pressure pump are struggeling to keep up. The Rosstech wiki also indicates this:

Have you calibrated the HPFP correct in the software? I do not think this is the problem, but this could maybe fix the differences between requested and actual in the lower RPM where the LPFP seems to do fine.

modules overheat and turn off, then error happen because presure is lower than specified.
