Gas gauge help please.... Car died

wh1te370z

So td on my way back to wrk on my lunch break my car decided to die. awesome right? so i call the dealer and explain to him that i got off an exit ramp went to accelerate and the car had no power. then i pushed the clutch in and the car died.. so he says heres a dumb question, do u have gas... so i go yea i put 20 in last night... turn on my car and i have nooo gas... no warning light no beeps nothing. no gas and my range is flashing 76 miles. so apparently SOMEHOW i went through about a 1/4 tank of gas in about 50 miles... i dont see that being possible. so i put gas in the car, it starts up and drives..

I live 10 miles from work and i had 3 dots on my gas gauge. way more than enought to go 10 miles. i dont have a gas leak that i see yet. im bringing it to the dealer tn and they are going to look at it tm..

So does anyone have any ideas? bad gauge? bad fuel level sender?

My car only has 5200 on it
