Tank float switches are bad for sticking and corrosion build up interrupting current flow. No biggie I am more worried about the no start condition. I suggest reading the sticky on the 6.0ltr forum first post.
Asimple quick test is disconnect the icp and try to start the engine, if it starts and stays running, you have a bad ICP or pig tail. The disconnecting of the icp causes the PCM to use a default set of values to start the tuck on. Basically it lies to itself that you have over 500 psi High pressure oil and its ok to fire the injectors.
If the rest of the HP oil system is good the truck will stay running. If not further testing is required.
