Car starts fine when cold, but once it warms up, starting it up takes very long after key is turned. Sometimes it takes so long it drains the battery. But next morning starts up with a touch of the key. Where could the problem be?

Check fuel pressure with a gauge, the pump may be giving a problem after warm.
