I have a 2003 jeep G/C 4.0 It shuts off everyonce ina while while driving. The engine light is on. Codes are 0455 and I think 0442. Had my shop look at twice. Pressure tested everything, replaced relays, test fuel pressure and replaced fuel pump relay. Still does it, Will start back up after like a hour of sitting.
