H20 reboots when accessing "recent searches"

[Bosco10021]

I am asking for some help with my Directv receiver.

Recently my H20 has been rebooting everytime I do a program guide search of "recent searches".

After this happens, normal viewing of guide shows only a few hours ahead as all infomation is shown as "to be announced". This does update eventually.

Has this happened to anyone else ?

Is there any solution ?

Thanks in advance for any help or suggestions.
