Possibly, you have a broken timing belt.
it could be of running it with out oil.
One posibility to check would be the timing belt. If it broke while driving your car will stall and will not start again. If it was the timing belt you may have a more costly repair bill then just the belt.
Sounds like the fuel filter is plugged. when did you change it last?
It is possible it is one of the speed sensors.
depends on what car and what engine, typically if your cruising on a freeway, you will be running at half RPM or at the most 3/4, but the lower RPM the better with that you get better gas mileage.
On the open road or freeway with mild inclines.
Running out of gas, timing chain breaks.
check your coil
The fuel shut off switch could have tripped, reset it if it has.
well my car today stopped running while driving the freeway .i took it to the mechanic and said i didnt have any oilnow i need a new engine :(the engine will seize up pdq
IDK yup
check your crank sensor
