Another overheating issue.
Alrighty guys im hoping you can help me out here. <br />
What ive got: 98 f150 standard cab long bed with a 4.6 romeo engine. <br />
<br />
The problem: On my way back to school today, just cruising down the highway about 75mph (2100rpm) when I see a CEL and temp light. Engine goes into limp mode so I pull over. Turn truck off and check engine. Rad hoses are hard, resevoir has coolant (and theres a spray of it all over the drivers side of the engine bay like the fusebox and such). No visible leaks. Let it cool for 5 min and its below op temp. Get back on the road and about 3 miles down it gets in the red. Shut it off before limp mode. Let it cool again and limp it to gas station. There, I took out the termostat thinking it stuck. Hoses were soft before I left (engine running). Didnt help. So now im sitting here infront of an autozone 5 miles further down the road. On the way here the engine would fluctuate from op temp to the edge of red, almost dependent on if I was going downhill or not. It didnt seem it help keeping the engine at low rpm (~1500 via 45mph) to help a collapsing hose. Additionally when I pull the throttle cable and watch the hose it doesnt appear to collapse. These are the two main issues that ive read on the truck, do yall have any ideas?<br />
<br />
Im not sure if this should be in the drivetrain section or here in the 97-03<br />
So I apologize if thats the case. And thanks for the help in advance.

Update. Replaced water pump last night. It looks in alright shape. Not seized.
When I was draining the rad to change the pump I completely removed the drain bolt and it only trickled fluid for the first 15min. After that it sped up on its own to a slow drizzle. I dont see how it could be a blockage I flushed it 8 days ago.
