UNO with WIFI Shield CC3000/Keyes works for some hours and disconnects

my problem is: I have and arduino UNO with a wifi shield provided by KEYS. It Works pretty well for some hours, then it disconnects from Blynk server and the only way to reconnect is performing the reset in the wifi shield or by opening Serial Monitor in the Arduino IDE. It seem that wifi signal maybe is lost, then the SW in Arduino keeps running in a loop that seems to blocks itself.
Is there any help?
Note: I use as per your settings in the ARDUINO/EXAMPLES/BLYNK the library from ADAFRUIT. Is this related to my problem as long as i use KEYES?

There seems to be a problem with the cc3000 chip. See thread here:
