Unknown prob anyone help please!

I have a 94 5.0 that i bought about two years ago but here is my problem... for the past month or so it started giving me this really wierd problem. One morning i tried to start it up but she wouldn't fire up, just kept cranking. i left it alone for the entire morning and later came back out and she fired right up. now it just got worse. sometimes it starts up and other times it doesn't almost as if it wanted to start up whenever it feels like it. but when i do get it started, it dies out on me after about 2 or 3 minutes while idling and wont start back up after that. one day recently i got it started, went inside to grab a cd and when i came back out it was off but i could hear the fuel pump whining and the check engine light along with the battery light stay on and will not start up again after. I have taken it to 4 or 5 different mechanics and none can tell me what is wrong. i took it to an electrician and he told me to take it to the Ford dealer and have them check out the CCRM which is right next to the Coolant reservoir tank. the battery checked out fine at Auto Zone i bought about a year and a half ago. also when i get it started and take it to any mechanic, it doesnt give them any problems, it fixes itself but when i bring it back home, it starts acting up again. any feedback would be greatly appreciated, please help anyone im about to go out of mind with this problem! Thanks.

Yea im pretty sure it might be the CCRM because i bought it with a Clifford alarm already installed on it and it has the Auto-Start feature and when i try to turn it on using the little remote i can hear the fuel pump come on as i said earlier, i feel the fuel go through the fuel lines and right before it cranks i hear a little clicking sound coming from the CCRM so im guessing it has to be that or maybe the dam Clifford is interfering with another wire since its hooked up to the ignition coil... i think im not really sure how that works but yea i will have to get it towed to the dealer if i cant get it started. Thanks

ok here is the latest with my unknown problem... when i posted this up on saturday, i had it in a shop getting checked out and i picked up later on that day. the guy told me it was the temperature sensor that was not letting it start up in the mornings so i took the car home it drove fine all day. the next morning i started her up but immediately died out on me. after that it did not start up until about 3 or 4 tries. i left it alone the rest of the day and then yesterday i got in and it started up fine did not die out or anything so i decided to take her for a run and pump some fresh 93 octane gas. she ran great all that time everything was smooth. Now i got home this morning from work and i just tried to start her up and guess what.... NO START! just cranks but does not start. I appreciate all the replies with ur guesses but my problem is im not that knowledgable on all this stuff so most of the stuff u guys told me to do, i usually take it to my mechanic for him to do. another thing is that, like BOS-94-003 said, its tricky cause u cant make it do it so when i take it to my mechanic he says he cant really check anything unless he gets it to do what it does to me. So is there a list of the main things that could be causing this? or could it be just anything?
