2011 6mt died when coming to a stop, wont start

[sidewinder_x5]

hello all,

was driving the z last night, and noticed a rattling coming when under 1/8th-1/4th throttle. also noticed oil temps slowly going up towards 240 (unusual when cruising at 80 on the highway), so pulled over to the side of the road, and just as i was about to come to a stop, the car died. attempted to start, but the started would click, and not turn over, and the SES light remained on. no codes that my reader could catch. called a tow, attempted to get a jump, but still nothing.

the worrying thing is the fact that there was barely any oil on the dipstick. this is odd since when i checked about 1500mi ago, it was slightly under the midpoint of h and l. i find it hard to believe the engine ate that much oil in 1500mi, and its only been 3k since my last oil change.

car is currently at the dealer, waiting to be looked at. in the mean time, does anyone have an idea of what could have happened? im already thinking worst case, and looking at used engines
