Where is my fuel filter at? Have looked everywhere

The fuel filter is pretty much non serviceable by anyone other than a repair shop! .. I'd rather think it's more likely a failing 'crankshaft position sensor' based on your post and experience repairing this type of problem .. Highly recommend testing at the time the engine stalls and will not re-start At the shop, we normally hook up the applicable testing equipment and let the engine run until it stalls, then testing can commence.
