engine stalling

I have recently bought a 94 eldorado cadillac that dies on exit ramps with a curve. It seems to only die when I have been on the highway and exiting off on a ramp with a curve. The dash lights and radio stay on. Starts right back up with no problem. It states monitored systems ok. I was told it was probably due to dirty fuel filter. Had the fuel system cleaned and filter replaced. Still does it. Intermittent problem. If you might have suggestions I would appreciate it. I have posted this twice and then can't find it after I have posted it. Hmmm. Thanks
