Exclamation GOT ISSUES/ DONT GET IT... NO POWER, Gets worse as it warms up

This thing is driving me nuts.
Ive changed all filters even the screens in the tank. new fuel exc...
its kinda hard to start when cold and has a little power to move its self in the driveway only and it will idle OKISH when cold... But as it warms up it get worse and worse.. It the temp gauge starts moving it wont idle, or pull it self... Only idles or runs with the go petal on the floor.. If it dies you gotta really crank it.. Funny thing is when it does this the oil pressure gauge is low WILE CRANKING.. The pressure will go up to 1/2 way up the gauge and it will start trying to start.. When its running the oil pressure is normal. This may or may not have anything to do with it. Has check engine light on ONLY when running.. I cant pull any codes when its shut down.
Seems like a HI pressure oil issue? bad hpop? ipr injector o ring blown?
what do you guys think? clasic sign of the HPOP failing?
Took it to the dealer and they said it has a bad # 6 injector and a bad fuel pump.. Well i put a new pump on it and it is no different.

check your oil levels, are you leaking any oil in the engine area? mine did a simalar thing, i was low on oil, added a little extra, and been running fine ever since.
