The problem could consist of quite a number of variables. I can only speak to my personal experience with my 2000 Stang. I had a similar experience and, to make a 'very' long story short, it turned out to be the electric fuel pump. I ended up dropping the tank, replacing the pump & filter. It hasn't caused a problem (with the ignition) since. However, I did have a heads up. I purchased an OBDII diagnostics unit and pulled the code that led me to the problem. I also bought a Haynes repair that has proven to be extremely helpful for years now.

One question: have you tried running diagnostics to see if there are any codes?

98 gt's had problems with the fuel pump. bad check valve in them, it won't keep pressure to the injectors. when was the last time you changed plugs & wires?

ok is there a better fuel pump that i can get and put in? also i havent changed the plugs or wires yet i was waiting for the spring time. btw i dont have any check engine lights on should i run the diagnostics anyway? however i was thinking fuel filter may be dirty. also something easy to start with.

changing the fuel filter is cheap, easy and only takes a few minutes so if you've never done it maybe now is a good time. when you turn your ignition to on can you hear the fuel pump run for a few seconds? you can test your fuel pressure by attaching a fuel pressure gauge to the schrader valve on your fuel rail. i'm not quite sure off hand what the acceptable psi range is, but you can find that in a manual or online. Also, you might want to try removing the iac and cleaning the inside with carb cleaner
