Check your timing. I have a 96 that did the same thing and the timing belt had jumped a tooth.

ok dont mean to sound dumb but im tryin to think about how to check the timing of the cam and crank and ive come up with 2 solutions 1 being to take apart the front of the engine take the timing cover off and checking the alignment marks, or checking it with a timing light if its off a tooth the timing should either be way off stock cuz its picking up the cam timing vs the crank timing so but like i said i dont want to sound dumb but thats my hypothisis. unless there is an easier way to do this please let me know.

My truck used to behave exactly as you described. It would run great when you first fire it up cold, although it sometimes died when pushing in the clutch to stop. Once the truck got warm, it wouldn't die. While warm, sitting at an idle for over 30 seconds, the motor kinda dropped off and started idling funny. When leaving the stop the motor would hesitate and immediately catch up with itself and run fine until sitting at idle for over 30 seconds. Over a span of 3 yrs dealing with this I did my research and replaced the idle control valve on the back of the throttle body. Reset my truck brains and have been driving it a year since then and still no problems. No more idle issues, no more dying of the motor. Don't even try and clean the idle valve, its not gonna work. Maybe for a day but the fact of the matter is that the rubber diaphragm inside gets dry rotted and gummed up with carbon. Your only making it worse with carb cleaner. Just buy the valve new.

Okay fixed my issue.

The problem I had was the second cylinder was low on compression. Do a compression check on your engine and make sure the compression is correct. My second cylinders exhaust valve was not sealing properly and I was low on compression in that cylinder.

I know it does not sound right, but the thing would run fine for the first 5 minutes or so and then I would have issues. Only reason I can figure for that is that the engine was running in a choke state which supplied more gas upon startup and when that stage was complete the engine tried to run off the leaner/normal fuel capacity from the injectors and fuel system then I wold have issues.

I ordered a complete rebuilt head off of Ebay free shipping for $350 and replaced it myself. Replaced a bunch of other parts on the way out as well water pump, timing belt, thermostat, etc. I have been driving it now for about 6-9 months with no issues and 26-27 mpg. I have a long commute to work bout 80 miles round trip.

Hope this helps someone.

Edit:
I did the whole Idle Air Control valve brand new and it did not help my issue as it would not with a low compression. So, if you have changed or cleaned the idle air control valve and it did not help your issue then check compression.

I too wrestled with my problem for over a year until i checked compression and that was the issue.
