Primary fuel filter

[tree98]

Sounds like something is clogging that filter prematurely. 10 micron sounds big for a 2350. These newer engines with the high pressure rail and super precision injectors usually take a smaller micron, my X15 spin on is a 4 micron. I would look on quickserve to find out if your using the right filter. Maybe take your current filter off when the engine starts to get doggy and cut it open, see what's in there.
