Try plugging the unit in at work or home and letting it play for several hours. During this time, have it hooked up to Hyperterminal (see FAQ). If it fails, see if anything appears on the serial port at the time of failure. Then do a hardware test after the failure as instructed in the FAQ.

I have done several trips from Northern California to Los Angeles and back, and the empeg hasn't failed during these journeys.
