Mileage? Mods? Condition? You gave almost zero info so I'll assume you tried to re-start immediately and it didn't work? Did it crank and no-start? No crank? Crank slow?
Could you hear the fuel pump run (ignition on) before no-start?
The only sensors that can kill the engine is the Bank angle sensor, side stand switch (if you have one) or temp. Temp could do it but it would run noticeably poorly first. You'd have limited RPM and even single cylinder shut down well before the ignition kill temp. Unless theres a very rare anomaly of it reading max temp instantly. A datalog would answer that (ECMDroid).
Before you go googling a replacement sensors as a 100% guess, it's much more likely your ignition primary system is compromised. Fairly common on a 16 year old motorcycle that the connections and handlebar switches get corroded. Check fuses and relays (especially the IGN relay), sometimes just the act of wiggling to remove them and replace them is enough to help a 16 year old connection get continuity.

Ya, ya. Check your grounds...

Check for codes, if no codes.... probably the cam position sensor

Good guess, the CPS does like to fail with heat. You can test that guess with a heat gun or hairdryer in your garage.
I thought replacing the CPS had solved the problem of engine turning off when hot, but yesterday 20 minutes into a ride the engine died checked for codes and nothing this time the fan ran for 30 sec(other times no fan)after sitting 20 minutes when turned key on red oil light stayed on.Started up and ran fine after sitting 1 hr. CPS was new from ST Paul HD.So the heat is affecting something and is ok when cools off Any ideas will be greatly appreciated.

I'm seriously starting to doubt your diagnosis skills. Why wouldnt the oil light stay on if you have the key on before you start the engine?

Your oil light is on (key on, engine off), and the light shuts off when it's running!?!
That is a definite clear sign that you need to find a mechanic. Because you aren't one.

Maybe its time to read this.

To wit:
NOTE
The oil pressure indicator indicator lamp will illuminate when the ignition is turned on prior to starting engine.

OK sorry for the poor explanation, as I reread my post I see my error.So I just went out to my bike, when I start to crank the engine the oil light turns off.What was happening at the side of the street when the bike would not start was when Icranked the engine the oil light was staying on.I have a printed copy of the manual.I really like my firebolt, and would love to know why it keeps turning off and I admit my last post was not proof read

Unable to decipher your trouble-shooting or failure-scenario jibberish....but simple to narrow down and resolve with simple answer. When this thing shuts off...is it as though the kill switch has been placed to the OFF position...or does it give the impression of running out of fuel? As in a more gentler shut-down scenario? Answer defines solution which is typically unique to these R models. And the cause was never a failing CPS. Hoping you retained your original.
Ok problem started last summer. I did spray with starter fluid and ran for second. Had more time in Dec and checked fuel pressure it was 41psi. Pulled fuel pump and one of the 3 plastic clips that holds the washer to keep pressure regulator in had broken off so as not holding pressure regulator tight. replaced housing and put fuel pump back in and fuel pressure was 50 psi.Runs great this year till temp gets 85degrees out. When engine dies seems more like out of gas.After it sits (cools off) for about a hr runs great again

Again. Unrelated, and something it's been doing the whole time you've owned it.
Sorry buddy, the honest truth is that you don't even have enough experience to communicate clearly or follow instructions to solve your problem. You're in over your head. Everyone knows it, except you. Even IF you were to get lucky enough and swap in the right part, it will cost you (and me) more time, money, and frustration than it's worth.
It's time for you to pay a professional mechanic for help to solve your simple issue. Or go to school. It can be a rewarding career.
