I have had the crank sensor replaced, mass flow sensor replaced, upper and lower timing chaninig replaced, and computer replaced, and the fuel pump replacedI am still having the same problem. When I start it up it starts to stutter and if I dont push the gas it cuts off but it will start back up but when I drive it, I go a few miles and it cuts off and sometimes it will start up and other times it has to sit for a while for it to start back up

Welcome to the forum, I saw what you replaced, have you done any testing? Use a gage and check fuel pressure. When the vehicle stalls and refuses to restart, have a helper crank it, while you check for spark at the plugs. Remove plug boot, use known good plug in boot, place metal part of plug to metal part of engine, with engine cranking, watch for spark at tip of plug.

Any trouble codes?

You place jumper wire between A & B terminals of datalink connector, turn key just to on position, no crank, the check engine lite starts flashing, you count the flashes to get the codes, if there are any?
