Got a 90 ranger recently replaced the fuel pump, fuse, fuel filter, 02 sensor, because it had shut off, but just drove for 20 minutes and it happened again only difference was I turned the key over twice and it started again but haven't been driving far due to this what could it be?

 

Welcome to the forum

What engine?
Automatic or manual trans?

2WD or 4x4?

Is it shutting off at speed, or while idling?

Did you replace fuel pump Relay on inner fender?

Are any dash lights or gauges effected, like they also lose power when engine stalls?

When it shuts off is there a stuttering like running out of gas or does it just shut off like spark stopped?
