No Fuel to Engine?

I cleaned and oiled the K&N air filter on my Gen2 AE, and now the engine spins but won't start. But I had also removed the fuel tank to trace some problems on the Audiovox CCS100 cruise control, and spun the starter with no fuel to the throttle bodies. It somestimes tries to start but seems to be starving for fuel.
Suggestions?

Assuming one of the two electrical connections under the tank is the fuel pump, yes -- it is connected. I did get it to run for about 3 minutes just now, but it was idling at 650 rpm, and any attempt at revving just killed it.

I disconnected the battery and reconnected, just in case there was a problem with the ECU. No change there.

Probably stuck in enriched starting mode..... needs to warm up to at least one bar maybe two on the temp gauge. If you have ethanol fuel in there and it's a coupla weeks old, may have phase separation, dump in a coupla ounces of Seafoam (or some isopropanol) to take care of the water at the bottom of the tank.
Let fuel pump fully cycle and shut off after turning on the ignition. Anyway, give that a shot. Hold the throttle WOT if it won't start from being in enriched mode.

I've been able to get the bike to run several times, but only for 2 or 3 minutes at a time. It has been up to 850 rpm, but afer a minute it slowly begins to lose rpm until about 500, at which time it quits. Got a couple hundred miles on new plugs, but it almost sounds like not all are firing. Maybe I should pull them to see if any are wet . . . . ?

Well, we know you have ignition and are at least initially getting fuel... if not rich (plugs wet) then lean... let's say fuel pump primes the fuel rail like it should, then doesn't pump enough fuel after it starts..... fuel filter clogging up, fuel pump failing or water in the fuel..... try the Seafoam thing...
The other thing to do is go into DiAG nostic mode and see if there are any codes that can provide further clues......

My thought too- maybe the vent hose for the fuel tank was kinked when the tank was installed and now you're trying to pull fuel from a vacuum.
