For you guys that have responded to this post the CPS (crank position sensor) is not the problem it still won't run I pulled the T Max off and I'm going to send it to them tomorrow and let them see if there is a internal problem I'll post what they tell me when I hear from them Thanks !

Got another bike handy you can quickly hang the T-Max on?  You'd at least know if started and ran.

Just wondering if there is an oil pressure shut-off of any kind on your HD. 
 

I know this is grasping at straws but in reality it worked before and other than a routine oil change the only other changes were related to oil.

Yes I have several friends with bikes I may do that before I box it up and send it to Zippers. My bike is an 04 and i'm not sure if they have any kind of oil shut off I have never heard of or seen in my shop manual saying anything about these bike having a oil pressure shut off maybe some of these real good engine guys will see this and respond and let us know

Just saying everything is good and then you make a few changes to the bike and now a problem...
I think the first place to look is at the most recent changes.  If the bike ran good before and for 15-20 minutes after and then all hell breaks loose...it's most likely to be related to something you just changed or did. 
These bikes are very electrically sensitive, did you pull the main fuse before doing your work?

No oil pressure monitoring shut off switch.

No I did not pull the main fuse and yes I did install a Harley oil temp guage in the fairing and install a oil cooler during the process and I went back and unplugged the guage sensor in the pan and the guage in the fairing (undoing what I had done) I guess you would say I am almost 99.9% sure it is an electrical problem My buddy is running the same T Max on his bike he is going to hook my T Max up tonight on his bike and see what happens the way I see it i've not got anything to loose!

I do not have a stock ecm for my bike I converted it to EFI from carb using all new harley parts except for the T Max I borrowed a buddy's stock ecm and tried it it does the same thing. I know what you are thinking that his ecm wont crank it because of the difference of the TSSM but I used a stock ecm from a 03 SERK when I was doing the swap and they will activate the guages and cycle the fuel pump and even crank the bike for  2 to 3 seconds until the ecm finds out its not programmed to this TSSM I am going to plug my T Max up on my buddys bike and see if it will run his bike maybe this will eliminate a problem with my T Max

I'm probably way off here as this comes from a single bike and incident several years ago.  But I thought I remembered the following from a bike with an ECM and TSSM that weren't mated (though there's not a specific mating on the Marelli bikes, just the Delphi bikes).

Guy I knew had a Road King whose TSSM took a dump.  He got a used TSSM.  Pretty sure I remember the bike still starting and the signals and other lights still working.  Just no alarm function nor ability to programs fobs to the alarm.

Don't take this as gospel.  Was a long time ago and only one weekend afternoon he was telling me about it.  But that's the recollection.

Ok, thought about this more.  More I remember the bike didn't have alarm.  So it was a TSM and not a TSSM.  That'd likely make more sense too as I don't think there's password sharing between ECM and TSM when one TSM replaces another.

Ok guys just checked my T Max on my buddys bike it cranked right up so the problem is not with the ecm it has got to be fuel (right!) if I'm thinking correct my fuel pump is running but may have lost pressure enough to pass thru the injectors. what causes the loss of pressure and not flow ? does this make sense if not let me know what you think. I borrowed a set of noid lights that are used to check the injectors for pulse and I am going to double check them before I pull the pump fron the tank. remember I can start my bike with carb cleaner ! and when it died it had been running for 15-20 minutes at idle.

If the lines inside the tank aren't perforated there is also a pressure regulator.  Have also seen the line from the tank to the intake collapse internally.

fuel line from the bottom of the tank to the injector block seems ok fuel flows free thru it one of the first things I checked. I'm leaning more to some problem inside the tank with something the pump does run but i'm unsure if I only have flow but no pressure doe's that make sense ?
