Intermittently Dies
I'm a couple days into a 4200 mile trip and my 1991 Tioga Arrow motorhome (Ford E350-based with 7.5L 460i engine) is giving me some problems. I'll be driving along and it will start to lack power but...

Thanks for posting the build dates. Yep, two pumps, at least one filter, and a filter/strainer or two.
Seems from your first post, that the external high pressure pump, and the fuel filter, were already replaced. Now, you have a new low pressure in-tank pump and strainer. In my opinion, that'll do it.
Could be the ignition module, but you have that covered too. I'd keep the used module as a spare.
It "might" have been possible to put an external LOW pressure pump between tank and high pressure pump. Back when the Fords had carburetors, you could pull fuel through a failed low pressure pump. I don't know if the low pressure pumps feeding high pressure pumps were like that or not. You're doing the right thing.
VERY confident this is gonna get it. Drive it and enjoy it.
