It might be a loose ground wire.

 

Also try this the next time it happens
see if you have head lights if so
hold brake put car in Neutral try to start if it dose
check tranny cable when you put it in park make sure tranny locks
in as if you leaned on the car it moves a little forward back you can fell it locked.
Or it might be the shifter.

 

how do i check the ground cable

 

for the ground cable you want to check the two main ones, the actual battery ground cable as well as the accessory ground cable, the battery one is the black lead from your battery and the acc ground should be pretty noticeable as well, not sure as to location someone with a three litre can help out with that..
i have to ask the extra questions, have you changed anything other than described with the last month??
has your car been worked on, especially by a body shop ?
anything else been changed or touched since it ran fine??

also don't disconnect your battery while the car is running the battery acts as a voltage stabilizer for your car, you can check static voltage on the battery, as well as charging voltage while running by hooking up to your battery posts with you volt or multimeter. rev up your motor and voltage at batt should increase to the neighborhood of 14 volts.
some alternators you can even ground out and full field test, basically a bad idea and completely irrelevant to a no start pretty much, but i do wonder since you had excessive corrosion if your voltage regulator was limiting voltage?
any strong smells around the battery? maybe swelling or visible vapors? keep you battery clean as well and let us know what's up..

 

Sounds like a classic bad starter. Replace it![sm=bounceybounce.gif]
