Just a little background, 2002 F-250 with the 7.3 284,000 miles. I just bought it. Doesn't seem like the PO did much other than changing oil, filters, etc. Anyway the last 2 days as I'm driving the truck will do a quick misfire like action and then it dies. I have had it do the misfire without it dying about three times, but twice it has died immediately. It won't start back up right away, but if I come back to it later, it fires right up. Changed the CPS yesterday after the first bout, and still had the problem today. After reading through several posts, I'm thinking maybe IPR, maybe even the seals on the IPR? Or maybe the fuel screen in the tank? What do you guys think? Thanks.
