What was it doing, cutting out at higher rpms? Stumbling a bit at idle?

I've been tempted to do the filter myself, since there has been a string of bad gas around here this past year, this may make my decision easier.......

Plus tonight I did something I NEVER do.. I let the gauge get to RESERVE, and when I punched it on the way home, the motor cut out from under me above 3500 RPMS... OOPS, I don't like sucking from the bottom of my tank!!

I had a miss under heavy load , like a cyl or cyls was cutting out, what had happened the fuel pressure was dropping due to a plugged filter.
I bought the car and was still chasing "demons" so it was a prosess of elmination Now it pulls at all loads with no complaint.
