I think NBHunter80 is right. A fuel pump will just stop the truck. Plus there should be an error code for it. An electrical problem can cause the truck to shake and run intermittently. This happened twice to me in the past -- it was a bad spark plug cable each time. Again, what codes is the truck showing if any?
Did the fuel pump solve the problem? I’m having the same issue. Truck warms up after 30 miles then starts shuttering when asking for more gas. Went to Nissan and they said it looks good for it’s age. No codes.
