I have really enjoyed this forum and have been able to solve a few problems from the suggestions I have read. So I hope some of you can help me out. I have a 2005, F250, 6.0 L, with 138,000 miles. When I am driving, out of the blue with no warning, it will just lose power. I believe it is happening when I am accelerating at least this morning. After a couple of seconds it will restart and all is well until it happens again. The truck never locks up. It happened once when I was out a red light and accelerated. It restarted without any problem. I have noticed recently when it restarts it will blow out a bunch of blue/white smoke. No indicator lights come on and lowest RPM readings are around 800. It did this around 50,000 miles, and the dealer replaced the EGR value (warranty), and the truck ran great until 118,000. I had to replace two injectors ($2, 010). At 127,000 miles the FICM was replaced ($1,050). And at 133,000, I replaced the EGR values ($206). Everything worked well for the last 5,000 miles. I add Diesel Kleen at every fill-up. I have put in some cost for reference (Raleigh, NC area) since I have seen people asking for them. Any suggestions before I take it to someone and give up my hard earned money?
Had this same problems turns out it was my EGR valve. When you replaced the valve did you clean down in the manifold? The lose carbon in there can get in your egr and hang it open causing the truck to stall lose power and blow white/blue/black smoke. Another thing is, did you look down in it with a flash light and see if it was wet down in the manifold? If its wet could have an cooler leak and that will clog up an egr QUICK. If you pull the egr start the truck with it out and rev it up it will blow the lose carbon out the top.
Thanks for your reply. I thought I cleaned it to hospital standards. I will pull it again, clean, and try the engine start. Better than paying some else to do it. Once again thanks for the suggestions.

With that many miles, you might want to check the ICP valve located in the front passenger side valve cover. Check to see if there is oil around the connector. If so the ICP diaphragm has ruptured and will probably need to be replaced. Stalling was a symptom when my ICP went bad.
