My car just started to just cut off after I brake to stop at light it will however start right back up. It also will not cut off if I drive in 2nd gear

Check the AIS (idle speed motor) the bypass passage may be clogged with crankcase vent sludge. This is a problem I found many vehicles

I am a Ford tech (35 years) and this is the cause of the problem in about 90% of the cars I see with this problem.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

it could be faulty fuel pump or coil pack transistor.

first check battery voltage. should be 12 volts or a little over. IF the battery is low then charge battery and then load test battery. If you remove you battery and take it to local parts store most will check for you. if battery load test good but was low on voltage then I would check to see that alternator is charging while engine is running. should be charging aprox 13.9 volts. if battery had full voltage and load tested good then most likely the starter is bad.
