Fuel gelling, or other problem??

[toolz]

Truck is a 2008 dually, 26,000 miles. Made a 300 mile trip today, tank was 1/2 full, went into regen, after about 5 minutes truck started loosing speed until I could only maintain about 25 mph. It was surging and bucking, no engine light. I limped into a fuel stop, fearing a gelling problem. Temp was 14 degrees. (Any fuel should handle that, this time of year). Added a double dose of Howes, topped up the tank. Off I go, regen indicator still on, and now a check engine light also. Same problem, 25 mph. Fuel filters were changed about 15,000 miles ago. If I got some bad fuel, I can understand why it reared it's ugly head during regen- fuel demand is a lot higher. It stayed in regen for over an hour, never quit. Possibly because not enough fuel flow to heat the DPF enough to shut it off. Dropped it off at the dealer at about 9 pm. I'll have them change the filters and check it out, but do you think bad fuel is the problem?
I think I've had enough of this DPF. I will search this forum for a solution, but I'm looking to delete it at a reasonable cost. I'm satisfied with the horsepower, so I'm looking for a simple kit to get rid of the DPF and get the milage I should be getting. Any suggestions would be appreciated. I'm a tool distributor, and the local Ford dealer is a strong customer, so warranty issues will not be a problem, as long as I take the truck there. Thanks for your help.

SCT with the DPF/DOC delete is how I would do it. Let us know if we can help.

A friend at the dealership checked out the truck today- Unfortunately he brought it in the warm shop to check codes before he test drove it. Code was low fuel pressure somewhere (no surprise), but when he drove it, still in regen, it ran fine. The filters looked like new. He talked to Ford hotline, but they hadn't called back by the end of the day. He's convinced something is wrong, other than ice/gell in the fuel. He checked a lot of stuff, including the 5 stages of high pressure oil- all within 20 psi of spec. Hopefully he'll fix it, but the DPF is coming off either way.
