Hitachi 470

[Quarryop]

Hi all glad to join the forum as it looks busy and looks really helpful. Hitachi 470 has issues I'm driving, It runs fine for 2hrs in the morning then on about the 2hr mark it cuts out like a fuel starvation problem. It will start again after about 20 seconds of turning over but then goes like a pig the rest of the day cutting out at least three more times and down on power like fuel starvation. When I start her the next day digger will spew out white smoke between 5 and 10 minutes until its warmed up then run perfect for the two hrs again. White smoke is defo over fuelling as it smells like that and eco consumption gauge is running at nearly 300 percent compared to 30 percent without the white smoke at tick over. Fuel filters were changed before the white smoke issue as old ones were blocked, and all rubber fuel lines have been replaced as they were rigid and hard to see if it cured the issue. engine warning light comes on when she cuts out the first time in the day and stays on. Message on LCD display says "check engine or engine related components" I personally think its an engine component faulty as you could nearly set you watch when she's going to play up on the two hour mark? Any help greatly appreciated
