truck starts then dies!

wondering if anyone could give some info, hopped in my pickup this morning about -6 outside, let the heater warm up go to start it starts fine runs about 30 seconds i hit the high idle then dies, then turn key off and restart runs about 5 seconds and dies, does this about 6 times then starts and barely keeps running, let it run for awhile and warm up. head out on the road and let it warm up and the dpf says its full and cuts power in half, only pops up on the mileage dash and says dpf and overhead says go to dealer now, wont tell me how full it is. Any info is great considering the dealer is 200 miles away and cant get it there till thursday afternoon.

Thanks Kyle
