Seems like you have a possible power supply interruption somewhere intermittently and such problems are not easy to diagnose unless you are able to perform testings when it occurs,

Check the connections under the fuse box for poor connections. Have a DVOM handy. When problem occurs, use the DVOM to test the power supply from battery to main fuses and fusible links.

Thanks for the info! I thought the same thing, just haven't checked it with a multimeter yet, i'll get on to it before it happens again.

Found the problem! Just don't know what its called. I think its a fusible link located at the positive battery terminal. I think i can repair it but really need to replace it. If anyone knows the name or part number please reply, will appreciate very much!

Hello sir, this is my first time in a forum so please forgive me if I screw it up. I really need your help. I have ran to the same problem with my 2007 toyota yaris. The only thing i did not do was disconnect the battery and reconnect it. How were you able to fix the problem? A mechanic looked at my car today and wants to charge me $300 for identifying the problem, he says is the junction box and wants to replace it and charge me $1200 for the whole job!
Once again how did you find out what the problem was? And how did you fix it. Thank you for all your help.

Respectfully

Henry

A power supply connection is loose somewhere and one way of testing is to use a DVOM to check for missing links. Try tugging lightly at the fusible links attached to the battry positive terminal and checking to see if things stops working.
