95 F250 idols fine for 30 sec, then shuts off

i have a 95 F250. It was running fine earlier in the day. i got back home shut it off....30 min later, it started to poor rain, i left to go out, it started right up, and then just shut off as if i turned it off. turned the key again, the glow plugs wouldn't warm up and the check engine light came on. i then let it sit for a few min, the glow plugs warmed up, the engine started right up, 30 sec later, shut off again as if i turned the key off....what could be causing this?

Cam Position Sensor usually. Dunno if they had trouble in the OBS though. Ford replaced mine like three times before they put one in there that didn't burn up.

Id say something to do with injection control module? If it starts then dies.
