Agreed, if it's not the usuals (sensor related), check the LVC. The LVC is pretty sensative, and if you pull too much load out of weak batteries, it can cause the LVC to kcik in. I had this a number of times when running it on auto, so now always manually set the LVC to either off (and time the runs) or 3.0v.
