7.3 eng runs rough then dies
late 99 SD with 225k miles, manual trans. Truck is well maintained, with minimal issues.
Driving yesteday just fine, them truck started to run real rough outta no where. pulled over, it eventually stalled, no restart. No CEL, Good fuel flow out of drain valve w/ key in run (tank 1/4 full), oil level good.
Put in new fuel filter, pulled chip, unhooked ICP sensor with no change. Truck seems to start if let set for 20+ min and will again run rough then stall, almost like not getting fuel? Its 20*F +/- here in SE MI, but ran fine on same fuel last week when it was -15*F. Not one to just throw parts at a vehicle, prefer to troubleshoot and diagnose properly. Any thoughts are much appreciated
