madaming pwedeng panggalingan ng problema bro.
check the following
-air filter
- spark plugs
- fuel filter
anong gas kinakarga mo? stay with 95 RON and up
feeling ko electrical related yung problem ng oto mo, pa check mo na din yung lines.
kung fuel-related kasi yung problem, medyo pupukgak-pugak muna bago mamatay.
The same thing also happened to me before (my ride is an EFI vehicle also). It turned out my alternator was already defective. I had to have it replaced. Most probable reason your car shuts off is electrical. Have it checked by a competent shop, have him do an isolation test.

Correct me if I'm wrong. AFAIK, if the alternator is defective, the battery take up the load, until its drained. Since you were able to restart the car, then that means your battery was still charged.
Still, it won't hurt to have your electrical system checked.
