I have a dodge 2500 2004.5 bought new in July 2004. Has fuel pump in tank. Has superchips tuner installed on tow mode. Was driving and it died. Changed filter on side of the road and it started and ran for about a half a minute then died. checked filter, cannister was about out of fuel. Filled it up again, replaced filter, cranked awhile, started, ran for about a half a minute and died. No check engine light, no codes.

Brought it home on trailer, figuring it must be lift pump in tank. Replaced lift pump, filled filter cannister, cranked awhile, started, ran for about a half a minute and died. Had P0148 code and some other code. If you turn the key on and off 3 times then crank it starts and runs for about 10 seconds then dies. Removed tune and put back to stock, now has no codes with the 3 key switch method but still doesn't run very long, about a half a minute.

Need help standed at home.

Just checked it again, It has P0628 code now.
