Unhappy Engine Miss Fire Under Load

Hi, I have a Dodge 2001 Ram 2500 with a diesel engine. Resently, while traveling down a very rough road, I started to get an engine miss. I checked the codes and the problem was the MAP sensor. The wiring plug had come loose. I put it back on properly and the miss disapeared. How ever, I have now noticed that while under a heavy load (towing), the miss comes back. No codes are being generated. any ideas?
Fuel Presure is about 15 PSI during the engine miss.
Is it possible the the MAP Sensor was damaged?
