Baffled! Starved for fuel.

[loub]

I have been having a very intermittent stalling problem with my 1994 850 N.A. since Oct. 2011. I replaced the CPS in Dec. 2011 which cured a hard starting problem. I replaced the fuel injection relay (Dec. 2011), had a clogged catalytic convertor replaced Aug. 2012, replaced O2 sensor, fuel pump (Bosch insert) which cured a cranking ,no start condition on Nov. 2012 and replaced the 103 fuel pump relay on Jan. 2013 (cured another cranks:no start condition)!
Yesterday I was exiting an expressway off ramp when the engine started to stumble (felt like it was starving for fuel). The fuel gauge was at 6 gallons, I was able to duplicate the problem 3 more times! I filled my tank today and was not able to duplicate the problem. Sounds like a fuel tank baffle problem,has anyone experienced this? Sorry for my rambling,but I wanted to be thorough.

A fuel restriction problem would be more likely to manifest while accelerating, no?

I'd suspect an air leak. Decelerating, you have very high manifold vacuum. Any leak in vacuum lines or anything in the air intake system past the mass airflow sensor would manifest itself most strongly then: the system would think there was less air coming into the engine than there really is, so it would ask the injectors for insufficient fuel.

I have seen fuel filters cause this problem on various cars, several times. I always start with the cheap/ maintenance possibilities first.

Sorry,I did not make my problem clear. My problem was happening while accelerating making a curving right turn around a loop and merging into traffic, I even took the right loop quickly and the engine actually died,I was able to pull over to the right and restart up immediately. This only occurred when the tank was lower than 6 on the fuel gauge,when I filled the tank I was unable to duplicate the problem.The problem was always when accelerating. Thanks for the replies.

Maybe the fuel gauge is inaccurate.
