Oxy 66 250 Hp -1998 starting issue

[Milton F]

250 Hp Oxy fuel injected- starts fine and stalls after warm up, will not restart. First incident idling for 1/2 hour, rough restart then ran strong back to mooring 4000-5000 rpm no issue. Due to one faulty low psi pump 2 years ago all three replaced. Note can restart again but repeats fault.
