I have a 1999 escort se 4 door with 29,000 miles . I was driving the other day and the car suddenly started to loose power and the gauges flickered. After getting the car stopped I tried to restart it and it clicked like a dead battery so i put the jump box on and it fired right up drove it a few more miles and let it set and idle for 45 mins. Battery checked good and so does alternator. I replaced the alternator with a reman unit just to make sure that wasn't the problem. You can drive the car for a little while and it will do just fine until you hit a bump or rough road and it shuts off and acts like the battery is dead. You can jump it off and it will idle and run fine as long as you dont hit rough areas. I'm thinking it is a ground problem somewhere but I'm not sure where to start.

idk much about 3rd gen but check to see if its your fuel pump cutting on and off by jumping it at the eec test (if 3rds have one) and go hit a bump, after that i wouldnt know where to look maybe blast the MAF with a good cleaner and hope for the best

These cars are known for having issues with the small wires attached to the negative battery terminal.

On my Escort this summer, it stopped charging because one of the wires close to the alternator had broken internally. It was a small wire, not the main power wire, so I repaired it by soldering on a couple inches of new wiring.

WELL!!! Back to square one , car has been driven everyday for a week with no problems until this morning. I was driving along and the gauges went nuts and the car died, the battery was dead and I jumped the car off was able to drive a few miles to work and it died again while I was pulling in the parking lot at work.

Does anything not work in your car ? (like blower motor, switches, buttons etc) Start at whatever doesnt work and check for melting/heat damage or a short , if you have a multimeter itll help alot but idk how to use a meter so someone else will have to tell you what to look for.

Everything works on the car as it should when the battery is charged. I do believe it is a ground or wiring problem. I was just wondering if this a common problem and hoping someone could help point in a general direction. I don't think my original theory on the bumps are the problem, I think by me charging the battery that the car is running off the battery and not the charging system until the battery finally dies. I've replaced the alternator twice with reman units from autozone hoping that was the problem but when these alternators are checked with the equipment in our shop at work they check good.

Have you tried actually checking that the car is charging the battery? What is the battery voltage with the car idling?

Carry a cheap voltmeter in the car. Also you can get a cell phone charger that has a built in voltmeter. Knowing those numbers can give you a lot of information. The battery should read at least 12 volts while turned off and about 14 volts when running. If that is not the case then there is an issue that needs to be tracked down.
