Engine is starting to quit

Driving along and truck starts to buck a little then motor dies. Starts right back up and may go a day or 2 before it does it again. Seems to be getting more frequent. 1989 chevy with a 350 motor 115000 miles.

Change the fuel filter and check the fuel pressure with the engine under load. Then, tell us the results.

I agree with hellokit. It may be a fuel problem. If that checks out you may have a bad ignition module. Inexpensive and easy to replace.
