cranks but won't start warm

[Everz]

posted this in the wrong section giving it another go, Ive read around this forum for a minute trying to solve what the issue could be, yesterday i replaced the camshaft position sensor, after push starting 3/4 times to see if it would just go away and i could continue work, and it seemed to start up fine but today it started doing the same thing. basically i drive on the freeway for an hour park for 20 mins and it won't start back up without a push though it cranks. ive checked the fuel pump and it looks pretty new, it runs great when it starts and has a brand new k&n air filter and i believe it gets spark due to putting in the new cps and battery has good charge so I'm wondering what it could be. it starts great cold with no issues whatsoever, i know all these things need to run is spark air and gas so any guesses? ill be pushing my truck somewhere in sherman oaks to start it back up now  if anyones around haha, 

 

let it sit for The time it took me to write all that and it started right up not a good long-term fix any guesses

Have you checked the coil after it’s warm to see if you still get spark? We have heard before that the coil can get heat soaked and not function like it should.

just drove home bout an hour, turned it off let it sit for a minute and checked the spark on the coil, it makes contact and has spark and started effortlessly, so thats not the issue i assume? might just replace it anyway to make sure thats not the issue. maybe my truck just don't like the valley haha

These trucks can be finicky. It has something to do with the electrical gremlins and the Renix system. A lot of diagnosing and using a multimeter go hand in hand with these Jeeps of this era and can help to not fire the parts cannon at them.
