won't start when hot, loses power on hills

[cokeman92]

03 6.0 starts fine cold but after its warmed up it won't start. Have to use ether to get it started. Loses power badly on any kind of hill. Idles smooth, very little black smoke comes out when trying to go up hill. Any ideas to what would cause this?

I had the same issue but no power loss. Changed out my ICP Sensor and Cam Positioning sensor. Now I am pulling no codes but still no hot start. Runs like a champ when running. Try changing out ICP sensor located on passenger side valve cover, then try Cam Position Sensor located behind power steering pump on driver side. Best to do this from underside of truck. Use 10 mm socket with at least 6" extension and you won't have to pull power steering pump.
Anybody got anything else that may cause a hot start disruption?

byron, mine was doing that to, just loosing power on a hill. Dealership has been working on it for a couple of weeks. If the ICP sensor or Cam sensor are messing up will it throw a code? ill run this by them tomorrow... thanks

Sorry it took me so long to get back to you wareagle. To answer your question, yes, you will pull a code. P2250 is the code I got. I unfortunately have a multitude of problems...still no hotstart after changing out my ICP and Camshaft position sensor. Now I think it is either the High Pressure Oil Pump (HPOP) or the crank position sensor. My next bet is the crank position sensor. I lend myself to this possibility since my I have very little power loss or hesitation on hills. I can barely sense one and if somebody else is driving, they don't notice. That's why I am going after crank position sensor first (and that it is the cheaper solution).
Keep you posted.
