Recreational Vehicle Lpg Tank Valve/gauge problems of the 2005 Dodge Ram 1500

While driving my truck straight down rememberance road (secondary highway) it stalled, loosing power steering and power brakes. I was traveling at a speed of approx 45 mph with no turns, coasted to the shoulder put in park and restarted luckily there was no other traffic. Truck restarted and I proceeded home. I parked the truck all seemed fine. Went out the next day and truck would not crank. Battery load checked ok, if I jump the starter relay @ pin 30 to 87 truck will crank. When key is turned on the dash lights come on along with radio, headlights, and blower for heat/air. This truck only has 56,000 miles on it and has been very well taken care of by me. It should be noted the gas gauge did not move when ignition key was turned on even though it had half a tank, it worked fine when I parked it. I have searched on line for this stall condition for my 2005 Ram 1500 4. 7l 4x4. It appears to happen alot if you search this condition on line with other Dodge vehicles also and is very dangerous, what if I had been on the freeway doing 70 and lost my ability to stop or steer this vehicle out of harms way. Well the most obvious answer, I wouldn't be here writing this complaint. I am so upset, as a cancer survivor and all I went through with that, it would be a sorry way to be injured or die. I have instructed my love ones to take action against Dodge should I die because of this trucks issue of loosing power. This is an ongoing problem that needs resolved by a recall or at least a thorough investgation of the root cause. I believe this is related to the pcm. I have had it towed to a garage to be looked at.
