What is your fuel level, fuel pressure, and do you have the ble spring update? Could be hfcm failing, or suction foot in the tank is bad.

Did spring update that helped a lot. Thanks everyone.
Still does it when pulling. Fuel pump is going out. Can the pumps be replaced with out buying the whole pump from ford.

Yes, you can buy just the pump from a site sponsor, Ford, an aftermarket seller, Amazon or even eBay. Sometimes you can find a new complete OEM HFCM for about $150, but not usually when you need it yesterday!

I recognize it seems to be related to higher speed and fuel consumption, but have you checked your FICM voltage or ICP pressure?

[flpaul]

No haven't checked any of that stuff. Will test next week.
