Automatic Start, after engine stall???

[TRD_1320]

While I was at a stop light, my engine just up and stalled without warning. Before I could reach for the key to try to restart the engine, it started itself... how convienient, huh? KINDA SCARY THOUGH... I went on through the green light, decided I would try to limp home (around the corner). As I apprehensively cruised down the residential street, it stalled again... This time I noticed that the BRAKE warning lamp was flickering, dimly. The engine again, started itself, then stalled, then started itself again (all while in FRIGGIN DRIVE)! I rolled into my driveway in a daze as the engine again stalled, started itself, then I noticed that the starter seemed to remain engaged... I shut it down. I turned the key to the ON position (not far enough to start the engine) and it started itself, again... Anyone have a clue what I might be dealing with here?

The engine died 3~4 times enroute to Toyota dealer. It died again while I was explaining the problem to the service writer, twice.

The dealer had the truck for almost 7 hours, could not find any problems. They claim that they drove it around rainy So Cal several times.

Here's a clue: when I left the key in the vehicle, I disabled my alarm (Viper) by setting it to valet mode. Toyota connected my truck to their diagnostic equipment and could find no explanation.

I am thinking now that I may have a problem with the Viper alarm. Even though my alarm remote unit has no Remote Start button on it, the internal circuit board may be equipped with Remote Start. I plan to bring it back to the alarm installer this weekend.

What model number on the alarm? It does sound like something a remote starter would do but I can't emagine how an alarm would do it. I sell DEI alarms and have no idea unless maybe it has a loose ground and was back feeding into something. I don't do installs on Toyotas much anymore but I am pretty sure the main electrics on that truck are not run by the CPU. You have to physically connect the wires in the ignition to get it to start. It's not like some new cars like the new Colorado. With that you only have 3 wires in the ignition switch. One 12v constant, one ignition, and one accessory. When the ignition "sees" 12v and the accessory wire "sees" 12v then "sees" it go to ground, the computer starts the vehicle. You can actually turn the key all the way over for a 1/2 second but the car will start perfect.
