Recreational Vehicle Lpg Tank Valve/gauge problems of the 2015 Ford Mustang

My engine has randomly shut off three separate times now. I have about 12,000 miles on mt 2015 Mustang gt w/pp manual transmission. The first time I was parked and it was idling, my friend and I both witnessed the idle dip, then 3-5 seconds later the engine shut off. The second time (was much more dangerous) I was changing lanes because of a car fast approaching from behind, I downshifted from 3rd to 2nd gear (30-40mph), let out the clutch smoothly, pressed the accelerator and the car did nothing, I looked down and the rpm was at 0 and "press clutch to start" was displayed on the gauge cluster screen. I quickly depressed clutch and restarted engine and took off to avoid an accident. The third time happened today 3/15/2016 I was again at idle and the engine just shut down without me touching anything, it again displayed "press clutch to start". I've read in forums that many people are having this issue intermittently, this could be a serious safety issue that can have deadly consequences. Please address this issue correctly rather than sending everyone home with the "we didn't find any issue" go-to response. Hopefully people don't have to get injured, or god forbid die, before this issue is taken seriously.

Purchased the car brand new Nov 2014. The 1st occurrence was around may or June of 2015 on a city street and I was slowing down while in 6th gear with the clutch pushed in and then I pulled the shifter into neutral. The run active power caught my eye and then there I also so the the rpm was on 0. I questioned myself on this 1st incident that maybe I did something wrong. 2nd incident happened sometime in sept 2015 and I was on another city street in 4th gear getting ready to come to a stop at a red light, with the clutch all the way to the floor I placed the shifter in neutral and I had a feeling that the car wasn't on anymore and looked at the gauges and saw that run active power was on again and rpm was on 0. This time I kind of started to suspect the car. 3rd occurrence happened June 11th 2016 and I was on a highway slowing down from 55 or so and push in the clutch to neutral and while rolling in neutral around 40 to 45 mph I saw the rpm go straight to 0 and at this point im convinced there needs to be a recall. All 3 incidents I quickly started the car back up while rolling. Also since I've purchased the car I've had the display randomly say that all of my drive modes are unavailable, traction control unavailable, hill assist unavailable, and a few more. 1st time I noticed that was while sitting in traffic, and 2nd time was on a random start up. I believe this could be a computer issue.
