1989 Buick Century 4 cyl Two Wheel Drive Automatic 130k miles

my car just started stalling out on me. The check engine light will come on while the car is in motion and the car acts like it has no gas. Sometimes it will start right back up and run fine but other times it is as long as 30 minutes before it starts back up. I have been using fuel injection cleaner with every tank fill up since this problem started. Do you have any advice?

Hi, how long since a tune-up? Check for trouble codes. You should be able to get some mil codes. You use a jumper wire between the A & B terminals of datalink connector. Key on engine off, the mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes. After you check for codes, When it refuses to start, have a helper crank it, while you check for spark at the plugs.
