That's a sign the Ficm is on its way out my friend, mine is doing the same, so I have a 58v unit from quick tricks on the way

so if im reading the others the votage should never drop below say 46 right because when i turn the key on its 46 or so n as soon as it starts it starts dropping n the batterys are good the battery votage when i start it up is usally 12.3

As long as your voltage is good then yea the Ficm is getting weak, mine does the same thing and it's been gettin worse over the paste couple months, so I just want to change it before it leaves me stranded somewhere and not damage injectors or anything

Mine did run for while at voltage in the 30's. I had no choice had to get home on a 2k miles trip towing the RV. It failed to start at lower then 30 volts.
The unit will only get worst and effect your injector coils. Taking a big chance of doing damage.
