I have a 1992 Blazer. I really need some help. It has been starting just fine when cold, but once warmed up it doesn't stay running unless I work the throttle. After working the throttle for about 30 seconds to a minute it runs and idles fine. It has now started randomly dying at stops. I start it back up and runs fine after. I did a fuel pressure test on cold and hot engine and the fuel is getting to the throttle body. Not sure what to do next, does anyone have any other suggestions.
