Power steering quits working. I can stop, shut it off, restart it and it works again. Happened 3 times today. What do I do?

You have some defecting sensors.

I am assuming you mean you loose power steering when the steering wheel locks up, which would be a normal event if the engine dies. Same goes for the battery light since the alternator would stop charging the battery.
Someone will need to figure out if you are loosing fuel or spark when the engine dies, then troubleshoot the problem. It may be difficult to find if the mechanic can not duplicate the problem in the shop.

Is the battery dead

Alternator not charging

Fuel pump fail

Check for codes

Sounds like the same problem I have been having with my 2002 Sedona for
the past 6 or 8 months. It would run OK for several days, weeks, or months,
then just quit. If I let it set for 10 to 20 minutes, it would restart and run fine
for at least the rest of that day. About 2 weeks ago, I was fortunate that it happened when someone was with me, so I was able to determine that it
was not getting any spark. Since then the problem has gotten worse and
more frequent - it was happening almost every day and would take over
1/2 an hour before it would start again. This morning was the last straw.
I drove for about 4 miles and it quit. Took 1 hour and 10 minutes before it
would restart. Drove another 2 miles and did it again. This time it took
1 hour 35 minutes before restart. After 1 more mile, it quit again. Took 2
hours, this time. Made it another mile and BAM! - did it again.
My bro towed me home. I determined that it is most likely NOT the crankshaft position sensor, because 99% of the time they either work,
or they don't. Very rarely does it cause in intermittant problem. The most
likely suspect is the engine computer. That was always a likely culpret
when I worked on GM cars. Today I installed a $50 junk yard engine control computer. I am crossing my fingers!
I will know on Thursday, as I have a 50 mile trip to make.
I will post again on Thursday, to let you all know.

Bad connection between PCM and battery/ignition switch.

Sounds to me like your belt may be slipping on the front of your engine. If it is in fact the belt, (not being particularly familiar with Jeep) be careful if you do try and make it to your mechanic. Have some one follow you if possible and or carry a cell phone incase you need help enroute. It is most likely a serpantine belt and if it does brake you may loose power steering, battery charging power (alternator) and worse, cooling ability. (AC also if you have it) I would call your mechanic(s) for their advice. A serpentine belt is not that hard to replace if you or some one is know is mechanically inclined.

Hi
is it leaking from anywhere, quite common o saxo's they leak from the steering rack, they have a small circular seal that go's and drips fluid out of the bottom.

It is also quite common on saxo's for the power steering pump to fail, it's the same on the peugeots, this is most likely the cause so get that checked first, you can get one off ebay for about £30 and they are fairly easy to fit.

Hope this helps

have the power steering steering self tested for a defective steering assist sensor on the steering column

As long as the light is on the airbag system is disabled.

I would suspect that your clockspring behind the steering wheel is going bad. I would have someone with a scan tool that is able to retrieve trouble codes from the airbag system check it for codes to verify this. If so then steering wheel and steering column trim would have to be removed to access the clockspring to replace it.

Its a Chrysler !! What would you expect.
