I have an 03 F250 5.4 code P0720 comes up O\D light flashes and the engine stalls after idleing for 20 to 30 seconds. Just a smooth stop usually, but some times will miss then stall.
Will start up and go till I stop again. It is bad in the line at the drive thru 4or 5 starts. Shifts fine drives down the road fine.
Replaced OSS, IPSS, MAF, coils, plugs.

 

where did you get it checked, in dealer or general shop?

should check wiring, or connections.
