Failed Prints after long successes

[VonStrom]

I have had the last 5 prints fail
I had replaced the lcd a month ago when previous one had dead spots and I was getting holes in prints.
Now this one has printed holes in prints but doe snot have dead spots. 
It will randomly print parts of models. 
I have changed the FEP as the pervious was deff in need of replacing and have leveled the print bed, I have changed resin to see if maybe I had a bad batch,  yet I am getting partial prints every time 

Any help would be appreciated
