New Problem... "fuel filter"??

[GMCjunkie]

Mudder, thanks for your reply to my last post. The reason that I changed my fuel filter in the first place is, that Im getting my truck ready for some long hauls to Tx this summer. Last time I went, there were a couple times that my truck "studdered".. and so I thought I would just change it out. Prevenitive maintenience. After I changed the filter, I started my truck, reved it a few times and let it run for several minits. Well today I started to work and it just up and died on me, no studder no jerking, nothing. just died. I got off the road and she fired right back up, Air in the line mabey? I took a chance, got back on the road, it died at least 10 times with in 5 miles, a couple times she studdered first, I had to put er in N and fire up- while moving,,, was REALLY scarry as there was no where to get off the road. Finally made it to a church parking lot, called my sister, she came and followed me back home, My truck only studdered one time on the way back, then she ran just fine. What could possibley be the problem?? The ONLY thing that I did was change that filter.I know I have it in the right way and got everything back the way it was. Im at a loss
Thanks in advance !!
