We have a 2000 873G that acts like the safety kicks out the hydraulics, like you lifted the safety bar, while you are running. Also all the gauges go dead. Before it would run again in a little bit. Now it won't and the engine shuts down after a few seconds. Any ideas?

Can't tell for sure without the serial number(year means nothing on Bobcat, everything is serial number driven) but you likely have a digital instrument panel, if so press and hold the lights button for 2 seconds and see if any diagnostic codes show in the hourmeter display.
The serial number is 514146688*
It said none

The gauges going dead has me stumped. If it was just shutting down to protect itself then then I don't thing the gauges should go dead first. Check a couple things while we wait for some other minds to chime in.
Battery cables clean on both ends
All the fuses, relays are seated good and have no corrosion.
Pump drive belt(inside the large plastic cover on the left side of the engine) isn't broke or loose.
You could have one of several things going on. Battery voltage can cause funny problems. The controller works between 9 and 15 volts. Anything outside of that, the controller goes into protective shut down. There is no rhyme or reason to what symptoms you can get. Also bad battery connections alone can cause strange things. Problems with the 8 volt sensor circuit can cause problems like this. Even if you where to get codes, you can't 100% rely on them. One sensor can cause the 8 volt system to go funny, but the controller will think it is another. I think your most likely problem is a big old rub in the harness. I would flip the cab up and look real close to the wiring coming down from the cab. The connector where the cab meets the mainframe harness likes to have rubs in its general area. I wouldn't rule out the can bus wires could be damage. With that said, start simple and check all fuses and relays first. If I was working on it after that and if the harness looked good at first blush, I'd swap controller.
My husband went out and cleaned all the contacts he could get to and it is running right now. Doesn't mean it will keep running though. Will keep an eye on this post if we continue to have problems. He will check the harness later.Thank you all for your help.
If he cleaned the battery connections, that very well could have been the problem. He may also lucked and moved a rub wire the right way when checking connections.
