Hi, my name is ***** ***** for your question.I'm reviewing your question now, and will post back with your reply ASAP.
The first thing you need to check is battery water level and fill to just above the plates inside battery, don't overfill, then charge batteries fully, have batteries load tested, most auto parts will do this for free if you bring unit to them, (batteries do not need to be disconnected or removed to load test) if you do remove any batteries make sure to mark and take pictures of all battery connections to aid in reassembly.
Make sure batteries are charging once testing is completed.
If you had a blown fuse problem would not come and go it would not work again until fixed,
On these if battery amps or voltage gets low lift will stop to prevent damage to controls
Batteries cause about 80% of these types of issues and must be eliminated as a posible cause before anything else can be checked.
