Have you had your alternator tested? The same thing was happening to my gf's car and that turned out to be it. I believe autozone test's them for free.

Have you're battery tested while your there.

Quitting!!

When a vehicle quits while driving and then starts up again within a matter of a few seconds that is indicative of a voltage problem to your plugs etc,you are more apt to find out that it is your ECM not getting the voltage to where it is needed on a continuing basis or a fuel /fuel pump problem.

ok sorry about the late reply. and sorry about the bad working. first off battery and altenator are good second off it didnt start running again i put it in nuetral while rolling and tried starting it and it fired right up again. one more thing i was driving my car today and the raidio would cut out and the blinkers wouldnt blink; like the relays wernt getting enough power i think the problem is b4 the ecu. but how would i diagnose the problem and fix it? any ideas

gotta check all wiring including grounds like to the block and to the battery

If you are losing power and you think it might be before the ECM then i would troubleshoot the ignition switch,then follow the power source to the ignition and keep going backwards step by step.Good Luck

Could be a faulty ignition cylinder (what your key fits into on the column)...a bad one would turn the vehicle off while driving, and not turn it on when you turn the key. Also just check your battery terminals, make sure they are tight and there is no corrosion around them...a loose battery cable can do everything you just described, so can a bad ground...
