Checked both fuel pumps this morning using test connector (since I hadn't done that yet; only checked Primary), and pulling fuses on at a time, both giving about 51 to 52 psi. Do have a leak though because pressure drops off back to zero with a minute or two when pumps shut off.
Appreciate the responses, will report in as I have more data.

Yes, you have a leak somewhere, but I doubt it is causing the main issue. Typically tho, barring a fuel line leak, it is either injector(s) or the check valves (one in each of the fuel pumps.
Project for another day: note worthy is all for now. The slow leak-down wouldn't cause the issue you've described so far.
Far as fuel lines go, the stock plastic clamps on the fuel pump assembly on mine was leaking, apparently. A stainless screw clamp end that issue. (Justa thought).
