I have a 99 F250 7.3 currently running a Bully Dog triple dog tuner. I am having issues with truck while driving with it shutting down. It will run fine then all of a sudden the rpm's will fluctuate and then shutdown. The truck starts right up after. There are four codes that showing up: P1249, P0340, P1210, P1211
. I have replaced the ICP
. Ford dealer cant find a problem so I am asking if anyone has any insight.
