last year i had problems after beating the crap out of it for 5 years, so gave it to jack and have had no problems since. i have mine set up to record when i have a switch turned on, and stop recording when the switch is off, rather than an "auto" start with one of the pressure sensors. you -could- be experiencing some problems with the pins, or some other electrical connections. i'd take it to jack and have him check it out.
