I was rolling fast at 100 mph suddenly the engine shut down like i turn the key off then in a 2; minute the engine came back alive ,like water in the tank,or ignition,or its the oil pump ?

 

water, probably not, oil pump=engine damage
my guess is ignition module over heated, what kind??
some ign have over current protection and will shut down but will reset with key cycle.

 

Check your circuit breakers out.

Check your battery cables at the terminals and ground.
