Question about 2000 GMC Yukon
2000 Yukon driving on highway at normal speed and motor just dies. Pull over to side of road and restart with no problem. Drive few more miles and continues to do that until l get home, what's going on
It sounds like your fuel filter has got to the end of it's life and needs to be replaced. Once the fuel filter get's to dirty, the fuel pump can no longer keep the proper fuel pressure to the fuel injectors to have them work properly. The fuel filter should be replaced once a year or 30,000 miles to ensure that it's always clean. A dirty fuel filter will make the fuel pump work harder and shorten it's life time causing a costly fuel sending unit replacement. Good luck and be safe.

engine and the automatic transmission in this vehicle are computer
controlled and in most cases when a fault occurs a fault code is
stored in the memory of the computer control module. There are
exception to this, such as the Mass Airflow Meter and fuel pressure
problems. What must be done is to have all the basic testing done
such as a scan of the system for fault codes as well as a check with
a live data scanner tool for engine functions that are not within
range of normal, a trained technician is required to know what is
correct and what isn't, then based on careful diagnostics done from
a factory repair manual the correct part is replaced or the wiring
repaired or the computer replaced (known as the PCM), which is very
rarely the problem. Other basic checks must be done as well such as
mechanical problems with the engine as well as engine state of tune
and mileage on the engine. The transmission can have mechanical
issues as well such as no gear engagement at all or a failed pump or
other pressure related problems.
