BR455;

Fist please go to the user CP and fill out your signature with your truck year and info see mine for an example. Please also tell us about how many miles are on your beast.

First thing you should do is CHANGE your fuel filter if you had not. The cost from $15-40 depending where you get them an all seem to be made by Stanadyne so quailty is the same. Second go over all your electricals AGAIN grounds included clean them and maybe even get some electrical cleaner spray and take all the plugs apart and spray them.

Here is a link to a trouble shooting area: http://www.thedieselpage.com/members/tt99-9.htm

This is a "members only area". If you haven't spend $20 and join, the resources have saved me thousands over the last 10 years. Between the subscription and ad's it keeps this great place going for us for the last 10 years.

Now if your stalling keeps up it could be the ill fated famous PMD/FSD problem.
Start taking liter of bottle water with you. This is a black square driver mounted on the iNjection pump. If it stalls again and if it is the PMD/FSD it will when it won't restart pour water on the PMD/FSD or put snow or ice on it. If it starts up it's very good chance that is your problem. If thats the deal do a search for PMD/FSD and you will get a weeks worth of reading.

Hope this helps.
