97 s10 help
i have a 97 s10 4.3 2wd. it runs when cold but once i warms up it dies and wont start untill it cools down. not getting any/enough fuel. fuel pump and filter are new 5-6 months ago. im pulling codes for multiple mis fire and 5 different o2 sensor codes. could it be the o2 sensors and if it is why would i only have problems when its hot? i dont think its the fuel pump. it could also be the icm or ecm to. i just dont want to spend a ton of money replacing all the o2 sensors and that not be it

Ignition Control Module
A bad ICM or ignition coil can break down when the temperature rises and function well when the engine is cooler. Those items should be replaced as often as you replace front shock absorbers. Some parts degrade so gradually that it not noticed until they fail completely.
