Have a 1998 dodge ram 2500 5.9L gas used for snow plowing. Just rebuilt trans last week, shifts fine, now truck bogs and stalls under load @ low rpm as if its run out of fuel for 30 seconds then runs great for 15 minutes and repeats itself, its make me crazy! Truck ran perfect for 11 years prior to this huge snowstorm. So far put dry gas, cap, rotr, wires and trans speed sensor with negative results. Please help!
