Got a issue with power engine has been inframed new turbo. engine will run fine for a few minutes exhaust has proper color but all of a sudden it will fall on its face and the exhaust becomes clear. shut it off for a few minutes and it will go again for a few minutes again. It is getting full throttle on linkage fuel pressure is 45-50 psi and don't drop when it loses power. Iam thinking a issue with the fuel ratio control valve any thoughts
