It will stay running as of now. when engine is warm it has started right up with no gas pedal
That's the sign of a bad engine coolant temp sensor. If computer is getting the wrong reading, it sends too lean a mixture. When you press the pedal, you override the temp sensor and it gives more gas

Possible weak spark from ignition coil or low fuel pressure due to weak pump. Try spraying carb clean into intake throttle body when problem is present. If vehicle will start and run with a little spray then fuel pump is failing.

I had the same problem but I did two fixes for it (1) when I bought the truck several years ago the duel tank switch was pushed in but i never fixed it and just would switch tanks with the switch pushed into the dash. after awhile it acted like it didn't know what tank to draw from point is i finally replaced the switch and it ran, but still ran rough, (2) on the left side of the motor their is an EGR valve (it was green colored vacum hose) I replaced that vacum hose and now it runs great.

Glow plug problem.Replace glow plugs with original Bosh. Also make sure glow plug relay box is working which is replaced under battery tray.
