not sure where to start
 

:argh::argh:I have a 2003 F250 superduty w/148000 miles & a 6.0..It has the banks intake-turbo&exhaust..& thats all i know about the truck right now..Mashed on the throttle 3/4 of the way topped a bridge down the other side to a stop sign & it shut off in the road..I had replaced the fuel filters about 6 weeks ago..thinking i had gotten bad fuel i replaced the filters again. both times i used microguard from the local guys..once a day i can start it @ idle for 5/10 minutes then shuts off again and won't start again without a little shot of fluid.. even then once you start it up & maintain 1000/1200 rpms it runs but let them drop & it dies again..any ideas what or where to start
