NHTSA Complaint #11527635 — 2013 NISSAN FRONTIER

This is an intermittent problem sometimes this problem will happen as far apart as a month, Then for two days then go away. When accelerating the truck will starting bucking, not getting to enough fuel, this will sometimes not stop the next day I take it to the mechanic it is running fine no check engine light comes on. He runs a diagnostic, no error readings this has been going on for 6mos.. Once it was so bad by the time I got it home it had fried the converters. The mechanic changed the converters replaced all the censors on the engine and converters clean the injectors, replaced the plugs, and changed fuel filter, tested the fuel pump, good. I need help, don't know what to do. Had another shop run a diagnostic check after all of this could find no problems, but the problem is still there. Afraid of stalling in an intersection and getting killed.
