What is your question?

My Nissan Titan if you gassed it one time, would spit and sputter but not die. We would kill it then start it again and it would be fine. Now it slowly progressed and now it's spitting and sputtering and will actually die on us. We have to kill it and start it back at every stop sign and red light and as were going well have to put it in neutral and kill it too. It acts like either the throttle body, fuel filter or fuel pump is acting up but we're not sure which it could be. We tried changing the IPDM and fuse box. Oh if you disconnect the battery it helps for and hour or less.
