Ok. What is it? As I don't believe in magically fixed transmissions. There has to be a cause to this. Your saying it's not the solenoids messing up. You saying it's not fluid issue or filter issues. So what could it be?
Or is it a transfer multimode issue?
I was just theorizing and trying to work through the issue.

The fact cycling the transfer case fixes the issue makes me wonder if possibly a failing/sticking transfer case switch is providing a false positive engagement? I have seen the detent switches cause weird shifting issues with the 4WD Systems of Tacomas, 4runners, and FJ Cruisers that have "old school" switches rather than ones internal to the actuator assemblies. I haven't had one cause quite the same issue, but I suppose it could be possible the actuator is getting "stuck" in a sort of limbo state because of a mis-reading switch?
I'm out of the house at the moment, but when I get some time today or tomorrow I'll check how that transfer case operates and see if there is a possibility one or more switches could cause it to do that.

Alright, had a few minutes to dig around and found a pretty good explanation of the VF3AM transfer case. I read through it a bit and I am wondering if your actuator is partially sticking and/or one of the 4WD switches is acting up. Going off the NCF documentation it seems like in 2Hi, the center diff lock is engaged, but it is disengaged as the vehicle shifts to 4Hi by way of the actuator. After that the physical shift lever engaged a different mechanism to engage the internals.
If I am reading this right (and it's possible I am not, got a bit of a migraine going tonight so it took a couple read throughs to absorb it...) then it could be possible that the vehicle is occasionally getting stuck in between engaging/disengaging the center differential lock and that's why cycling it all the way to 4Lo and back "fixes it." Would require some testing of the actuator and detent switches, I also can't explain why the vehicle would be getting intermittently stuck between a shift when a 4WD shift is not engaged. I do know that Toyotas like to put themselves in the selected 4WD mode when the key is cycled, i.e. if you turned the vehicle off mid-4WD shift it would try to resume the shift when you restart the vehicle (it's not a 100% thing, it's more just something they try to do), so perhaps because the actuator is sticky and/or a switch is finicky it could be thinking it hasn't completed a shift and is trying to get itself properly set?
That's kind of the only theory I have as to how the transfer case could be the cause of your intermittent issue, but my heads throbbing so I'll have to revisit this with a clearer head later.

Thanks. Yeah I think BlackWorksInc is on the right track. It is some issue with engaging weird. I assumed it was the transmission but I guess it could be the transfer case. When it works, it works fine. But 0.000001% of the time it doesn't work -- at all.

Damn good explanation with a migraine.
Now I'm wondering if shifting the transfer case over and over might solve the problem. Like rear locker and ADD you don't use them they act up.

I am suspecting the transfer actuators messing up. As I am not seeing anyone reporting this on the J shifter transfers.
I would think if the transmissions were doing it they would have failed by now or the issue would have been found.
This is just a guess though.
