I changed the oil in my bike yesterday and while the oil was out of the engine I installed a oil temp guage harley #75265-04a and also a Ultra cool fan assisted oil cooler. After the install I put the oil back in the engine and cranked the bike up it ran for about 15 to 20 minutes I was setting beside the bike where I could see the temp guage it was around 125-130 degrees and the bike just quit not a noise or a sputter it just died like the switch was turned off. I did not think much about so I turned the switch off and went and took a leak I walked back to the bike and turned the switch back on and hit the start button and the bike just turns over and over but will not start. Now my mind starts turning trying to think what may be wrong so I start checking, the fuses are ok checked with test light, double checked the wiring I did for the guage and the cooling fan on the cooler, pulled the spark plugs grounded them and spun the engine over spark is ok, checked fuel pump it's cycleing on and off like it should, so I start thinking fuel, I removed the fuel line from the top of the intake where it feeds the injectors and the fuel flows free to this point. I was thinking ok fuel ! I have cranked my off road cab trucks and jeeps with fuel injected engines after a roll over or getting water in the intake with carb cleaner so I turned the switch on cracked the throttle a little hit the start switch and give it a shot and it fired right up and ran for a second. The question is what have I missed ? what would cause it to just die all of a sudden and not start back up ? What is keeping the injectors from letting the fuel pass thru them ? just so you know I am running a T Max with Autotune and engine mods that I have put about 8 thousand miles on with out a problem if anyone knows what may be my problem please respond to this post it's looking like I may end up at the dealer if no one knows what it may be I've done everything I can think of

When you hook up your tmax do you show any codes?

No codes at all 

[Godeater]

Check your main breaker  Just an idea

[grahn1967]

Anytime power is disconnected,the E.F.I. module must be re-calibrated to engine sensors.

Not doing that repetitive on-off on-off on-off cycle wouldn't keep the bike from starting though.

Electric or Fuel can be the only issues.....

Electric OK then it must be fuel

spray fuel in throttle body?

if it runs then it has to be something with injecters.

what is the fuel pressure? 50 - 60 PSI?

This is the sequence I would try............

Diagnostics and Troubleshooting____________________________Always pull the ECM fuse before disconnecting or reconnecting the
battery! At any point if the ECM Fuse has been pulled, including battery
replacement, the ThunderMax ECM must be re-initialized. Failure to do
so may require linking to the module to fix the IAC Stops location
152
IAC Plunger Check
Entering from the throat of the throttle body, probe with a soft tool
like a spray tube from an aerosol can into the IAC port until you
reach the face of the IAC plunger. Make certain the handlebar switch
is in Run, turn the ignition switch on and then “off.” The IAC
plunger should extend out (closing the port) and then retract (opening
the port) to a home position every time the switch is turned off.

Go to page 151 of the smartlink tuning manual,that's a good place to start.

The circuit breaker is ok checked all of the fuses and relays first. Power to the ecm was not lost during the install of the guage but I did the switch on switch off three times just to be sure. It is getting fuel to the point of the injectors and the pump seems to be working ok. The bike will start right up when it's sprayed with start fluid. What is puzzeling me is that the bike cranked up and run at idle for 15 to 20 minutes setting in the garage

FUEL  IN TANK?

[SILVER ROAD KING]

FUEL  IN TANK?

Yes 3 fresh gallons very first thing I did

[SILVER ROAD KING]

I had one guy tell me it may be the crank position sensor what do you all think ? he may be right but the bike was setting in my garage and had been running for a good 15-20 minutes when it died and has not hit a lick since except when I sprayed it with carb cleaner 

[spydglide]

Check the fuel line connector for 'trash'/obstruction......it's been known to cause your exact scenario.  spyder

[SILVER ROAD KING]

I have already taken the fuel line loose where it connects to the top of the intake just before the injectors fuel flows free to that point I think I'm right in thinking that the injectors are not pulsing or spraying fuel since I can crank it with starting fluid. The guy that told me about the crank position sensor said in short that it can all of a sudden go out and cause the ecm to not get a signal to fire them he may be right
