Car runs for 5- 10 minutes then stall with loss of all electrical power. After 5-10 min power returns and car starts and runs for 5- 10 minutes then stalls with loss of all electrical power again.

Welcome to the forum, thanks for the donation. I'd make sure the battery has a full charge and the connections are good. There may be fusible link/s close to starter solenoid, check that also. If you losing ignition feed, I'd check feed to and from ignition switch.

There is a theft/security system on your vehicle, can't tell if that is causing a problem? You have to test when the problem is ongoing.

Thanks for reply
battery is 3 months old and shows just over 13 volts.
Connections at batttery and starter cleaned.
When engine stalls turned key off then try to start to find no power to anything
What could cause loss of all electrical power when engine stalls, dash lights, horn, headlights everything
then return after 5 min?
Also there is a sercurity light on dash thats always on but has been so for years.

I'd have to track a voltage circuit. It's easiest for me to pick one circuit that should have voltage and doesn't, then track the circuit. The horn, the fuse is underhood, passenger side fuse box, I believe. That fuse circuit is hot all the time, use a testlite. There should a remote positive battery stud, either in the fuse box or close, that is hot all the time. You'll have to do testing when the problem is ongoing, I'd have to backtrack the circuit.
