i notice you have a flyer listed,
i assume this is a power flyer ??
if so,i have had this very same problem before,and again now,
although my sys is a 1200t running 0s3.5,
the only way i can get my sys to work is the same as you are having to do.
on both occasions it turned out that my power flyer was/is
the problem ?
the first time it just gave up, now it was caused by my pwr supply acting up (over powering)
this is just a suggestion through what i have experienced
mines going back to elbox to be checked out
