general problems of the 2009 Subaru Tribeca

Problem 1. While driving on the interstate highway car lost power, stalled and shut off. The gas guage was on a 1/4 of tan of gasoline, miles guage read 100 miles. I was able to coast to the side of the road. Thanks god, I near the next exit. I was able to restart my car after about ten minute and went to the nearest gas station. This have happen to me twice on the interstate highway so I try not let the gas guage fall below 1/4 tank because the sensor are not register correct. I have take my car to Subaru dealer in jackson, ms 3 times they can find the problem. I travel the interstate highway daily to work, usually drive in the outer left or right lane so if my car cut off I will be able to coast off to the side of the road not at ran over. I took video picture of the guage reading to show to the Subaru dealer on my cell phone. Problem 2. Temperature gauge read the car is running hot while driving and sitting at stop light. The gauge randomly moves up and down while driving. I had take my car to Subaru of jackson twice about this problem. They keep may car for about a week could not get it to replicate the problem. I have replace my radiator and thermostat but that did not correct the issues. Since Subaru can not find what is wrong with my vehicle I don't know what else to do. Problem 3: low tire pressure sensor light randomly flash on and off while driving then stays on. I have had the tire pressure check several times. Pressure is fine on all tires. .
