Low Idle when pulling in clutch?

I'm having an issue that makes me nervous to ride.
Basically I went out on a ride a few weeks ago and about 3 hours in I pulled in the clutch to slow down and make a u-turn and the bike died. I chalked it up to user error but when I tried to start it, it wouldnt start. It clicked once. I cycled the ignition and waited a few minutes and it started right up.

An hour later, I was cruising on the highway and went to get off an exit, again, I pulled in the clutch to slow down and it died. It wouldn't start right back up again. I cycled the ignition and gave it some time and it started right up.

I replaced the TPS in hopes that it would solve the issue.
The other day I was cruising at about 50 and was going to make a left turn, I pulled in the clutch to slow down and i looked down and saw my RPM dip down to 800.
Normally, during idle the rps sit right around 1000 fluctuating 100 +/-.

I have a 2012 Fatboy Lo. Vance and Hines big radius, Fuel pak with the suggested tune from VH and a K&N Air Charger.

Any ideas?

Have you checked your primary oil? Could be excessive drag from the clutch. Does the bike try to creep when in gear with clutch disengaged?
Have you done any work on the bike recently? Chrome switch housings for instance?

Sounds heat related such as a failing CPS or temp sensor.

I just had all oils changed so that may be fair to check.
I haven't noticed any pull when clutch is pulled in.

The only work that I've had done on the bike is the fluid change, clutch adjusted and throttle/idle cables adjusted.

Funny you mention that, I completely forgot to mention that the 2nd time it stalled when on the highway, I pulled off, got the bike to start and immediately went to autozone to test the battery. The battery felt SUPER hot. Almost to the point I couldn't touch it.
I'm not sure if this was normal at all but the battery tested fine and I kind of forgot about it being that hot.

I was reading about the engine temp sensor and how it shuts off a cylinder when it gets a certain degree.

Is there anyway to test the cps or the ets or should I just replace them?

Bike has 13k miles on it. I bought it used at 11k and I have no idea what maintenance was done to it.

You might want to check the charging voltage, as a failed regulator could cause similar problems, and cause the battery to overheat.
Dunno about the other stuff...

The 1st thing I would do is check for codes. The procedure is in a sticky in the electrical section.

I found it. Thanks!
Sounds dumb, but I wasn't even sure I could see codes, so I appreciate the information.

I will definitely add this to my list of things to look at.

If this were bad though, would it have drained the battery completely and not let me start it after cycling/waiting?

Voltage regulators can fail 2 ways , no charge or over charge.
Overcharging give you excess voltage , your lights will be brighter, the horn will be louder and it can boil the water out of your battery , top it off with distilled water if the battery is serviceable.

Check the voltage at the battery when it is running. Let us know what it is.
