Need to replace fuel pump?

[Aimster]

I've had an SES light come on and off for the past couple months. "Camshaft position sensor".

I changed the fuel filter and it went away for 200 miles. It then reappeared.
I changed the air filter. It went away and it then reappeared.

Today I had 80 miles left on the tank and my car suddenly died. It turned on and died. I hit the gas and it would die. Sudden loss of power. I was lucky to make it home. Had to turn it on several times in 1-1.5 miles. I've had the same problem before but it seemed to have been solved with the fuel filter. Now my problems are back.
My only guess is.. fuel pump?

The only thing I have not changed on my 2001 3.0 with 102,000 miles is the spark plugs. I doubt that could be the problem however.
