I would try rotating the throttle stop screw in 3/4 turn- sometimes the back of the stop screw gets grooved, & rotating that screw presents a new flat surface for the stop to rest against ( and gives a pinch more air.)
Changed out the engine temp sensor just to see if it starts better tomorrow. We shall see in the morning. I am thinking the problem is in the tank. Ordered a new pump, regulator, filter, screen and gasket. Also ordered new bolts for the top plate. Should be here this weekend but I am out of town until next weekend starting tomorrow.
Fuel pressure goes to 58 with the key on and falls to fifty. While cranking drops to 30.
Once in and at idle stays at 58 psi
fuel pressure should not drop to 30 when cranking it should stay between 55-62 at all times.. maybe a weak pump, clogged filter, weak regulator, pin hole in line.. etc. i think that is your main issue here.
I believe I can hear the check valve hose leaking inside the tank. Replace it, the filter and inspect the regulator housing while you're in there.

Did you check the fuel regulator housing as rigidthumper suggested, when you replaced the fuel regulator?
Don't know about Dynas, but the early Twin Cam Softails had issues with the regulator housing itself cracking/leaking...
It was often enough that Trask designed, made, and sells a billet fuel regulator housing for the softails...

I just got my new to me 2013 electric diagnostic manual and I will post up pictures of doing a current draw test on the bike or on the bench. Any clamp on amp meter will give you the information you need to do the tests.
