This vehicle starts fine and runs good for a couple of minutes as we go down the road. Then for a few minutes it with loose power and buck on and off. After that it will run fine. This happens regularly. The engine light is off but does come on once and while. What is wrong?

Get the computer scanned for OBD2 code/s with or w/o the CEL

Could be an intermittent problem with the cam and crankshaft sensors or a fuel pressure issue/MAP and O2 sensors-/throttle position sensor/EGR valve

It not intermitted bucking but pretty consistant. Shortly after warm up it will buck for a few minutes and stop. How do I narrow it down to just one sensor? Will the computer read out do this for me? But it runs fine till I go down the road? Please help me narrow it down!
Thanks
