Report "I am haveing an issue with my 05' Titan and need some help. It was running fine and we shut it off to go in the store. When I tried to crank it back up, it fired up, but was acting like it was only firing on 2 or 3 cylinders. I shut it down and let it set for a minute or two and tried it again, but with the same results. I countinued this a few times and then it fired up and ran perfectly. We got it home and parked it. The next day I went to work and it done it 3 times on the way to work while driving. It just died in the middle of the road and when I tried to crank it back up, it was doing the loping. The "Service Engine Soon" light does not stay on for any codes to stick, it just flashes rapidly while the truck is having the issue and clears when it goes to running fine. I there anything you can reccommend that I can do myself?"
