Try a fuel line/injector cleaner you may have a blockage in the injectors causing uneven fuel delivery. I would also recommend new fuel lines or check current lines for leaks/blockages

General advice:After warming up track the problem:sparkplugs (even new can have the ceramic parts broken/cracked /wiring (after warming up the isolation get's soft,can loose spark power)/ignition coil(s) (gets hot,stop runnig),running reach,fuel pump/fuel pump relay.Best guess:fuel pump mallfunction (low pressure) related,fuel filter cloged/water in the fuel/fuel line cloged/chipped. Cheers,hope u figure it out,let the people know.
... first check to see if the check engine light is on ...light on and when was the last time u gave your turck a complete tune up plugs, wires , air filter and a fuel filter you will need to a scn tool to get the trouble code
Sounds like something getting warm/hot as engine warms up. Could be the MAP sensor, Coil/Coil pack, Ignition Switch(not the key cylinder), or possibly the Oxygen Sensor.
Next time it does this, pull a plug wire out of the coil pack and hold it close to the tower, and have someone crank the engine to see if your still getting a spark.
Could also be a loose connector on the throttle body injection, or a broken wire.
Hi! It wont past the filter if the Fuel pump is faulty. The fuel pump sucks fuel from fuel tank to the engine. If its faulty it wont have a fuel supply to the engine. Have it replaced and you'll be good. HOpe this helps and have a good one!
Yes the fuel tank will need to be removed to replace the fuel pump, be very careful and use only non sparking tools, there is a potential for fire and explosion..
