On my '13 Fiesta. Can't run pump a full flow. A slower rates works OK. I filled OK at my regular station. Drove to VT when the problem showed up. I laid it to the pump. Nope, got the same thing at my regular station.
I figure it has something to do with the venting. With the sealed systems we have, I figure taking it to the dealer to check out. Don't know if it has anything to do with the capless filler.
I have heard of other Fiesta's having this problem, never heard of the fix.
No CEL
