It used to bog down at 65.mph
I then had the spark plugs replaced and it still had the same problem starting but sometimes it starts just fine and now runs great.

Now recently it died as I was almost to stop and it started up and I parked it, a few minutes later I tried to start it and it would just turn over and over, but no start.

When I pulled the spark plug in the front it started up fine. Plugged it back in. It wouldn't start. Unplugged it then it started.

Put a new fuel filter in and it started up perfectly then parked it and went to start it a few minutes later and again it wouldn't start. Next morning, it started perfectly and ran fine at start up and while driving for a few days.

Today it started fine then I was almost to work coming to a stop and it died. Now it won't start again. Tried the spark plug and that didn't work either.

crank position sensor
IF it's the CPS, the car usually fails when the car is hot...car shuts down all of a sudden when it's really hot, and when engine cools down, car works again. If you notice that, then CPS for sure.

It could be the tranny, the same situation that you explain in detail happen to me, thought it was the sparks plug too =/ . My trany died at 92k, and the cost to replace it is heart breaking...

starting problem
It will be either the crank position sensor or the cam shaft sensor. Both of those sensors will cause that problem. Good luck
