6.4 powerstroke random fuel pressure drops

I have a 2010 f 350 powerstroke loses fuel pressure then returns to normal randomly. Replaced fuel filter (napa gold) solved problem for about a week happend again replaced filter thinking bad fuel didnt solve anything. Ordered motorcraft filter installed it seemed to solve issue for about 3 days. Ive dropped the tank its clean. Cleaned my fuel pump/ water seperator. It had very little in it. Idk if this is a related issue but since ive had the spartan tuner if i get in it hard and let out of it i get a low fuel pressure warning after i let off the throttle. Wot never misses a beat.. anyone had this issue?
