from KPHX, i requested a VFR flight following on app/dep frequency , and it was a complete silence each time . So, i checked the log as usual to see the problem :/

i would like an explanation of this part of the log where it seems to be the problem :

i started a new flight with vfr flight following before take off, and everything seems ok for now . So ... 

It's possible that the Grammar is not recognizing "Papa Five Two" as an airport, even though that is the correct code, the voice recognition is looking for a 4 letter code.  If you say "Kilo Papa Five Two" it might work.  Just another of those limits caused by dealing with a machine instead of a human.

i said "KP52" after , but no response : maybe, i was already out of the app/dep freq zone  ,so it explains the silence ... i don't know . Now, i prefer demanding vfr flight following before take off , the handling seems more fluid .

Anyway, i started a new flight from KGCN and now p2a stopped responding (with eternal wheel cursor) when i requested taxi to runway : i send you the log by mail . Hope you find the culprit ! 

Thanks for sending the log.  I found an error in the taxi routing that caused a problem at this particular airport.  It will  be fixed in the next update.
