Have it towed to a service shop that can fix it. I am guessing you posted this standing by the side of the road from your phone…, correct? No way for us to help you in that situation.

That’s one of the signs of a faulty crankshaft position sensor.

If the computer loses the signal from this sensor, the computer see’s no reason to operate the ignition and fuel systems, and the engine shuts off.

Sometimes letting the engine cool down allows the sensor to function again.

Possibly fuel pump relay…  
Wife had same problem with her Kia…  
Dealer techs could not figure it out after several attempts…
