After doing steering and brake adjustment last night, was feeling good about the truck (57 3600) so drove it to work today. 20 miles with no issue. Then a mile from work stopped at a railroad and it died on me, and wouldn't restart.

Strong starter noise, seems to have power. Plenty of fuel in the tank (I added more). I did get it to start once, but died almost immediately.

I had to leave it and walk the last mile into work. I'll be headed back to it this afternoon, to try again, and tow it home if I can't start it.

What else should I look at or can I try?

Thanks,
