09 yaris hatch has gone nuts

[kenora]

09 hatch le 4 dr auto 1.5 l ....I was on the highway yesterday when the car started hesitating.. I could feel it miss every few seconds..then it got bad enuff the cruise would kick off.. then the engine would actually shit off for a second and restart causing a major thump. It was as if the key was being turned off..on..since the dash would go black for a moment then illuminate again...
I had to drive in 3 instead of d due to the transmission constantly shifting to neutral and the rpms flaring to 5000 or more.. I slowed to 80 kph.
I limped to a family memebrts place and shut it down for the night.. this morning there was no response from the key..just a hard click from a solenoid under the hood.. I thought the battery was dead..its newish...
The electric locks would not work I had to use the key to lock it and the doors last nite
I opened the hatch this morning and suddenly it tries to start..the starter was engaged and turning the engine e over...the car wouldn't start but it turned over fora coupe of minutes while I tried to stop it...I put the key in the ignition and turned it to every position but no luck it kept turning over..then I tried to shift to drive and it stopped.
Open the hatch and it does it again..
It's getting towed to Toyota but really WTF?
