Need a little help troubleshooting. Yesterday, my truck began to shut off abruptly. Under every condition, from idling to slow runing(30mph), and 70 mph, to load and no load. Wait 1 minute and it would start and run for 1 minute 15 seconds. If the batteries were disconnected, the truck would run for 13 minutes before shutting off. Have replaced the fuel filters. Still does it, but runs for between 10 and 20 minutes before shutting off.

Am seeing only two errors codes. P1000, and P0603. I was 40 miles into the Ville Vidal, when this started, and 150 miles from home. To get home, I disconnected the batteries too many times to count, and bled the HFCM numerous times. Am also seeing the moisture in fuel icon on teh dash light up when it quits, but so far as I can tell there is no moisture in the seperater.

2003 F450 6.0, automatic. 150K miles.

Any input would be appreciated.

thanks in advance.
