Runs for 30mins and shut of. Need help ASAP!!
I have an 89 f150 4.9 with a 5spd.
New parts within the past 2000miles or less
Throttle position sensor
Idle air control valve
In tank fuel pump
High pressure pump
Plugs, wires, cap, and button
Distributer
Coil pack
ECM relay
Ignition control module
Thermostat
Fan clutch
What happens is it will run for about 20 or 30 mins then will just completely shut off. It will restart after my temp gauge gets to the cold mark then it will run another 20mins maybe. I am at a complete loss. I blow my heater core out a few weeks back and some nasty stuff came out of it. But this didn't start happenin till after I was goin thru my feild check stuff and hit a hard bump, wich is when the dist went out. Not sure if when that happened somethin else happened to or what. Any ideas would be helpful. THAnks in advance.

I would start by checking the wiring harness for obvious wear and tear. Make sure there are no breaks in the insulation. If there is, two simple solutions are electrical tape or good 'ol RTV. On the older trucks I owned I put RTV on the back of every connection to strengthen the wiring and to keep some water out.
Other than broken wires, fuseable links are where I'd start next. I believe there are 2 or 3 that have to do with your ignition system. By chance, have you looked at your ignition switch wiring? Maybe cracked in the steering column.

Ok so it just happened and i could smell the fuel after I cranked it over, I don't have anyone else to help me so I can't really check the spark but I'm guessin there is none.
