New Stalling is REALLY dangerous, HELP PLEASE!!??

[jetuomi]

Hey, I posted in July/August that my car was stuttering for a second or two (like I hit a curb in the middle of the road), and I did the following:

1) injector cleaner
2) checked battery cables, fixed ends

Now, it was fine for a 3000 mile trip to Winnipeg and back to Toronto, but, now that I'm back, its dying on me in the middle of the road (eg: driving on a 3 lane highway, and it just stalls, rpms drop to 0, and check engine light comes on, its scary, but, popping it into 4th from 5th, and a few seconds later, it turns back on, thank the lord) After it starts back up, my gas mileage goes DOWNHILL (almost like the computer has gone to open-loop mode, if there is such a thing) as I measured 50 miles, and it burned over a quarter tank at 1800 rpm's in 5th (usually, it gets 2x the mileage)

And, I know its going to stall on me, because its HARD to start, like, it could take upto 15 minutes to start... and then I know its going to stall on me within the next 1/2 hour, BUT, if it starts fine, it runs fine till I turn it off next..

This is really strange, and my only guesses are that; maybe the injectors are failing; or the Mass-Air Wiring (or ground) is not making connection... Any ideas?

(summary of problems)
really hard to start
stalls while driving any gear (not idling)
bad gas mileage after stall

THANKS A LOT GUYS !
