Probably the high pressure fuel pump failing. If you have a way to monitor or better yet log data from the vehicle, monitor/log the live data for high pressure fuel system pressure commanded and actual pressures. The high pressure fuel actual pressure should not deviate from commanded pressure by much at all. Within a few engine revolutions during cranking the high pressure fuel pump should be operating at full pressure. If your pump fails this scrutiny, do yourself a favor and do not buy an aftermarket pump. They are garbage.
