lumina 1999 LTZ cuts out

When I start out from an intersection my car cuts out. Sometimes when I'm driving 30-35 mph it misses and cuts out. I was even backing up the other day and it died. When I put it in park and rev it up and misses at 4000 rpm. I just took it in and had the plugs replaced...fuel filter and a complete tune up. 75,000 miles on it. The car still having problems after getting it all tuned up. Could it be a fuel pump or ignition control module or something else?

LumyLover,

I don't know why your Lumina is cutting out while being driven, but I know that when they are in N or P they are designed to cut out at a certian RPM to prevent over-revving the engine and causing damage.
