The model 3 works much better as an NTP/PPS host.

OK, I can try a 3.

Sometime it never comes back, if I pull the PPS to GPIO cable and 
reconnect it will work again (but not always)

We have seen this before, the HAT header wears out easily on the Pi.
Best not to do too many HAT swaps.

This is the first thing that has been plugged into the GPIO ports

address@hidden:~# ppstest /dev/pps0
trying PPS source "/dev/pps0"
found PPS source "/dev/pps0"
ok, found 1 source(s), now start fetching data...
source 0 - assert 1510148557.996485612, sequence: 438970 - clear  
0.000000000, sequence: 0

Is more than 1 per second is that correct?

Yeah, that is why it is called Pulse Per Second (PPS).

Yeah, but is was getting more than 1 per second, I may be wrong (usually am) but I think 1510148557 is the second and my post showed more than 1 a second:

It is strange , as it just sits there quite happily and then eventually barfs and looses NTP1.
