Cool glow plug relay issue

ok, I have a 1996 f350 7.3 diesel... I have been having issues with my wait to start lamp not coming on. if it does not come on when I turn over the ignition I know it will not start.. I have replaced the glow plug rlay 2 times this year... this last week it stopped on me while driving the truck... I replaced the relay it started right up... no issues... drove it a few times no issues.. I drove it to a friends house went out several hrs latr to go home and it would not start. I waited several hrs as in the past, it would start, and it didn't.. troubleshooting it the battery main battery, left front, seemed to be dead as I could not turn over the truck again. put in a new battery, started right up.. went to a couple of places and then home... next day, today, it started then immediately stopped and it won't start again... all of these have the WTS lamp not coming on. What is happening?

No wts light typically means no power to PCM. 10.5 volts minimum are needed to start a truck.

Is your fuel bowl heater unplugged?

When it fails to start, watch the tach as you crank it. Does the tach respond?
