My Truck listed above 4X4 5.9 94,000 miles has started losing power then shuts off while driving for no apparent reason then starts right up again. What would cause that? Also, can you tell me where the fuel filter is located? Thanks so much!

Hello,

It sounds like you might have a faulty crankshaft position sensor.
The crank sensor sends the engine rotation information to the ECM. Over time with heat and vibration from the engine it can lose its internal calibration. Which will lead to incorrect data to the ECM. This can trigger a shut down.
It can shut down at any random time and you may or may not be able to start it back up.

Here is a helpful guide:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
