Power Window problems of the 2000 Jeep Laredo

I own a 2000 Jeep grand cherokee Laredo. My Jeep has shut off on me three times this week while I was driving. The first time my cruise was set at 65mph, it kicked off the cruise and there was no power to the vehicle. I pulled over, restarted it got back up to 65mph and it shut off again not 2 minutes later. It didn't restart again for me that morning. My fiance went to pick up the vehicle about an hour later and he drove it home as if there was never a problem. Today (2 days later) while coming around a corner in town the vehicle stall again, but the steering column locked up this time and I had to immediately hit the brakes stopping the Jeep in the oncoming lane to avoid an off road adventure. Luckily there was no other traffic, but what if there was? what if the steering column locked up while I was doing 65mph down the highway? I use to love this vehicle, but now im afraid to drive it. I can't afford to have it looked at, I just got the Jeep out this afternoon because the passenger window fell inside the door and broke. My new window is now bolted to stay in the up position because I didn't have the extra couple hundred to replace the motor that was completely tore apart when the window came down. What's next?.

Front passenger window slid down inside the door. It is now shattered. I bought the car a few months prior with no problems , the window always worked fine. Now even the button to move the window does nothing. Glass needs to be replaced and also the regulator (window motor).
