i had a similar problem. my car would just randomly die anywhere it wanted to. and then id try to start it and it would start run for a few seconds with a almost stumbling idle and then die again. after stalling a few times the car would start like normal and ran perfect. i was told i needed to replace the fuel pump from the previous owner, but i hadn't yet. later in the month i unplugged the fuel pump and looked at the actual plug. the black wire was chared. i took a knife and cleaned that one terminal and pluged it back in. hasnt given me any problem since. my is also a 98 svt. try looking at the plg and repost if that helped any.
