Please help me!

When driving on CNG gas after half an hour of driving problem appears. Motor stops pull - cukavá ride until it goes off. I switch on the gas and go about 15 minutes. and then again, I can switch to gas CNG and again while I go on this fuel. Thus, it alternates.
To report a fault diagnosis P0170.
Injectors now totally new - no change.
After resetting the error P0170 again while driving and then the same problem.
Someone knows the problem? Please advice.
