cutting out
 
Ok please bare with me I will try to explain whats going on

I can start my jeep runs good when its cold, when it gets up to temp. It starts cutting out at about 2500 rpms, I have changed the intake manifold air temp sensor and the engine coolant temp sensor, its still the same I have been trying to figure this out for a while. Does it make sence that it could be the crank shaft position sensor or the cam shaft position sensor
Thanks for your time and help and sorry I dont explain things very good please ask questions if you need to

Have you checked the condition of your plugs, wires, cap and rotor? Check the fuel filter as well.

Does it bog down at 2500rpm or just shut off?

How old is the fuel filter? And what made you think it was the two sensors you just replaced? Is the check engine light on? Does it do it at 2500rpm with a load (in gear), or without a load (neutral)?

could be cam or crank sensor. all electrical parts can break down with increased temp. when they cool of they work fine. i would go with the crank sensor first. it reads the rpms anyway. if it is cutting out at 2500 rpms, then maybe it is the problem.

Ya I checked the plugs and wires and new fuel filter and have good fuel preassure. It dont shut off cuts out for a second in gear or in neautral

I have replaced the fuel filter and I replaced the sensors just from information I read in my manual, The check engine light is not on and it does it in gear and in neutral
