Help! Keeps stalling out...

[Crazee D]

Hi guys.
Having a new issue today and wanted some help figuring this out:

Where do I start? The car is far from stock....

This afternoon it decided not to crank over after I had been driving it around all day. Weird thing is, I could get lights to come on by wiggling the key and shifter (i have sport shift auto), but if I stepped on the brake *Poof* no dash lights etc. Checked the under hood fuse box and did not notice anything obvious.

Jump was successful. yay

Drove down street, turned on A/C. *Poof* it shuts it ALL down. No power steering or brake. I coast to a stop.
Key is now locked into ignition and trans won't come out of Neutral-Drive positions into Park. Same behavior as before, won't crank, lights come on when u work key in ignition.

Next jump successful.

The AAA guy said he saw a big voltage drop when we turned on the A/C but it didn't die. I turned car around to leave and it died again. It's going to be towed.

I have had similar intermittent starting issues when an exposed O2 sensor wire shorted out while rubbing against something.

Any input or suggestions?
I am really wondering if the lockout feature on the trans and brake is interfering somehow.

Have you tested the battery and alternator?

I had to get it towed.
But I will make sure those aren't overlooked thank u.

electrical bugs are a b**** to nail down sometimes

Well, a new battery solved all.
But I can't believe an Optima yellow top would just die after 4 or 5 years.

My son had one die in a year in a race car.
