1992 Toyota Celica hard to start and tends to stall when sl

So about 2 years ago my 92 toyota celica just wouldn't start wouldn't turnover at all so I took it to the mechacnic and they determined it was the distributor. Got it fixed and the car ran great for about a year, then slowly once a month it wouldn't start. I would pop the hood and give the wires connected to the ignitor a good shake and then the car would start. Then it started happening more often to now its everyday but now shaking the wires doesn't work I turn the key and hold it for about 15 seconds let go and repeat until it finally starts which take me about 2 mintues. My best guess is that the wiring is bad? But on top of that problem, when I come to a sudden stop the engine will sputter and most of the time stop. If I come to the stop slow it runs fine. I have no clue what would be causing this.
