Default 2007 f150 supercrew stalled driving over rough road

Well, last week I was driving my f150 over gravel and went across a rough stretch. As the truck was vibrating it suddenly stalled. When I tried to restart it, the engine turned over but wouldn't start. After sitting for a minute, it finally restarted only to stall again as soon as I dropped it into gear. This process reoccurred 3 times. On my fourth attempt the truck finally stayed running and I was able to drive it back to my garage. I'm a little at a loss to know where to start looking for the cause. Knowing it stalled over rough road makes me wonder if an electrical connection is loose. Anyone have an idea of what this could be or where to start looking? Thank you so much.

I would check your battery cables. Also, check the cables to the alternator and starter.

Ouch!


Thanks for your insights! I have checked the battery, altenator and starter cables abd found them to be solid. Then, I pulled off the FPDM to inspect it and this is what I found... (Picture above)

I ordered the Dorman replacement part (590.001) from Amazon Prime new for $58. It should arrive tomorrow. I'll install the new part and let you know how it goes.

Wowzers.

That FPDM is smoked!

Glad you figured it out.
