Ignition Coil
i had to replace the coil pack on #4 (pass. side all the way in the back) and it was a huge pain in the *** and plus there expensive. but it went out when i had like 57,000 miles. i noted though it had like anti-freeze on it or some kinda slippery liquid on it i showed it to my mechanic he said the heater hoses tend to "sweat" sometimes on these trucks so just as a heads up it maybe something to check
