One Low Fuel Pressure warning

2021 F350 Diesel showed "Low Fuel Pressure" one time while towing uphill and trying to accelerate. Went into reduced power mode for the rest of that drive and have not towed since. DTC 0087 was cleared and has not returned. Could this be the beginning of a CP-4 fuel pump failure?

CP-4, lift pump, or if the fuel level was getting towards E going uphill possibly missing the pickup?

How long since your last fuel filter change?

It could be, but if it hasn't come back after clearing and no other code popped, then probably not.
Change the filters if you haven't recently.
