The truck has had a weak start, began about 2 weeks ago. Friday night it wouldn't start at all after running it for a few hours out to eat and a few other places. Got home and loaded up the fishing gear and it wouldn't start. Cleaned the battery terminals and put them back on and it cranked up fine, no more problems. Sunday I'm riding down the highway and the truck cuts off in mid-motion doing roughly 35-40MPH, I coasted to the side of the road. Wouldn't start. Checked the terminals again, nothing. Got it towed to the house..
Here'* what'* been checked.
Positive Batt. terminal was busted, It was replaced.
Cap & Rotor were corroded, they were both replaced.
Fuel Pump fuse is OK!
Fuel Pump cuts on with the key.
Engine is receiving gas up front.
The engine turns and sometimes it will start, but it cuts off immediately. Will not run more than 3-5 seconds.
The starter has began making a weird noise, wasn't doing this before tonight. It sounds like the gears are stripped almost. The starter was replaced about 6 months ago. The power wire seems loose, the lug that holds it on just doesn't seem to get real tight, can't tighten it too much because it'* encased in plastic. I busted the lug out of the plastic housing when it was replaced and had to take it back for another one the same day.
Any help on the matter is appreciated.
Thanks.

If the main power cable to the starter isn't tight, that will cause problems in cranking as well as shut downs if it'* moving around. I would look at that area real close. It'* likely your problem.

Check your fuel filter making sure it'* not clogged. Then check your fuel pressure to see if you are getting the right fuel pressure.
Has your check engine light come on recently? If it has, I would find someone with a scanner and scan your computer.
