1999 died while driving

I work for a fire department and our 7.3 ambulance died twice on the way to the hospital. Both times were when it came to a stop. The rig is well maintained and the only mods are new belows for the turbo and a SCT programmer. I have noticed the overdrive light on the auto shifter blinking recently but have never had performance issues. Rig has only 40,000 miles on it. I know SCT is not the perferred tunes but its what we have. After it was started both times there was no loss of power and it seemed fine. Anyone have any ideas what it may be?

Probably the cam sensor. Get rid of the sct ASAP. The blinking trans light is a sign of bad things to come. Bad tunes only make it worse. In our 97 ambulance we just deal with stock tunes since there are so many different drivers. There's less of a chance to smoke the trans if you stay with stock tunes IMHO.

Ambos should never be sporting any tunes. Private or Government? You get people driving them who have no concept of wear/tear on a drivetrain. It's 100% GO and 100% STOP all of the time with nothing in between. I know in MD, public service equipment is and will always be stock (or else my car would be a lot faster than it already is )

The tunes we have a very mild and is set on the tow setting only a 40hp increase. We got tunes because we are located up a steep mountain road and the stock tranny shifted very softly and constantly searched for the right gear. In 2nd it winds out to 2800 rpms doing 35 and the speed limit is 40mph no passing lanes. We talked to the shop about the shift issues and they suggested a light tune to increase the line pressure and crisp up the shifts. It has made a hugh difference in drivabilty for us. The rig is not hot rodded but makes multiple trips up and down. I will change the cam sensor and see what happens.
