Your fuel pump or fuel pressure regulator are not supplying constant fuel pressure. Too much or too little is causing it to kill. You can pull the vacuum line from the regulaor and check for gas. If there is none, you need a pump, it is weak.
the track off light will come everytime yhe check engine light comes on. this is normal. you need to have the check engine light checked first.you can go to your local parts house they will scan it for so you at least see what area you problem is in and then you can start from there. let me know lf you find out youe engine codes.
The crazy part about it my car doin the same thing.Part of problem was I had got some bad gas from a cheap gas station( so watch your gas) I replaced fuel filter and pump (by car shop) and put in jet cleaner also. When I took car out shop it was still doin the same thing. I have changed the throttle position sensor and it seemed like it half-way fixed the problem, but now all it do is stall or cut off when touch gas pedal.
