After my 110TLB runs for 10-20 minutes it will stop moving. If I lift off the pedal it will start again and move a few feet.sometime gives beeper alarms that are not always the same. I can move it just fine using the creeper control. Already checked if I was hitting both petals at same time and looked for loose connection on phedometer(?). My shop manual says to try power cycle the computer. Is that just disconnect the battery?
