Will a pouch reset diet or a liquid diet and a fill get my lap band working again!?

The short answer is no.  Your story is typical for band patients.  Some patients originally do well and then regain most of the weight back.  Some do not even lose at all with the band.  This is why most bariatric surgeons are doing bands any more.  gastric banding does not work.  Consider a revision to a gastric bypass, duodenal switch or gastric sleeve.  

the band can be successful, but once band patients start having trouble it can be very difficult to get back on track. the most effective thing to do is convert to another operation (sleeve, bypass or DS) depending on other factors

Let your story be a warning to others.  Some people do well with gastric banding at least early on, but long-term failure rate is very high.  The esophagus can't tolerate the high pressures caused by the band and eventually gives out.  It's not too late to convert to another procedure that will give you want you wanted with the band.
