Recreational Vehicle Lpg Tank Valve/gauge problems of the 2012 Ford Fusion

Last Wednesday, 7/24/13, I was on the interstate coming home from work in the far left hand lane when my engine shut off and put me in a really bad situation. I had to cross multiple lanes of traffic, while not being able to accelerate, to get to get back to the shoulder. The car seemed to being working fine, but when I hit the gas there was no response. The lights, gauges, and radio still worked and a wrench light came on. I was nearly rear ended twice and barely made it to the shoulder. Today, 7/30/13, on my way to work the same thing happened. Thankfully this time I was not on the interstate, but rather on a busy city street, and was able to quickly and safely get out of the way.
