It's usually hard to figure out track problems without a diagram. We don't actually know where his loco is stoping, before the points, after the frog on the mainline or in the siding.
Depending on where the feeders are and especially if we are talking only one to each rail, switching to the siding will kill mainline power on the opposite side of the turnout.

Our dearly missed electronic Guru Randy Rinker had this to say about feeders and insulfrog turnouts (third from the bottom post)

I don't see one turnout to a siding as reversing loop situation. pending more information.
I would suggest to the OP to bite the bullet and go to Harbor Freight and get a $6 voltmeter. He can check continuity (it beeps) on one of his extra turnouts and understand how it routes power, what is hot and what is not. He can measure voltage. While it is true voltage can drop under load, most of our problems can be traced to electrons that have stopped moving somewhere.
Or he can rig up a tail light and aligator clips.

Thanks guys! Guess I know what I'll be doing this weekend. I sincerely appreciate the inputs!!
In essence you have added a reverse loop to your established single point layout. You will need to isolate a section of track and install either a double throw double pole switch if it is DC or on DCC there are auto reversing units. Be aware that ARs are designed for low amp systems like the NCE Power Cab and others for higher amp systems.

Good Luck, Ed
Have you checked the poliatry of the feeder wires to the siding?
Gentlemen, this topic has undobtedly been touched on before and elsewhere, but...
I'm working on a new section of my layout, which will include a DCC basic oval of sorts running around the periphery just as window dressing when I have visitors who just want to see and hear "the trains" running. I added ONE trailing point turnout, a Peco Insulfrog #6 that connects to a siding. Suddenly, when I manually throw the switch to move onto the siding...everything stops!! So I thought...bad turnout. Switched it out for another. Same thing. Then a third...same thing. I'll add jumper wires at some point, but.... any thoughts on what's going on? Or in this case...NOt going on? Troubleshooting electrics is the one part of this hobby i LOATH, so any advice would be appreciated before I toss something expensive at the wall....
