Truck usually after it has hits operating temp it will lose power & start to miss. It will idle perfect but will not pull it's self. If you shut the key off for a split second it will start & run normal for a short while, then do it again only sooner & sooner.I have replaced the relays, computor, fuel pump, plugs, wires, temp sender to the computor. About 3,000 miles ago I replaced the head, timing belt. This has really got me stumped!When it running it runs great but it seems to have develovped this problem. Could it be a ground everthing seems to be connected.

Sounds like it could be an ignition problem. Does it have a destributor, or coils?

It has a distrutor & a coil.I wonder if it isn't the part in the dist.I think it's like 150.00 or 200.00. This is getting really old quick!

Look in your distributor and see how it looks in there. Your rotor and points may be causing an arc prematurely. Look at the plastic near the points, if it is making an arc too soon, you may see hairline burn marks in the plastic. That's an idea you can look at atleast. Hope this helps.
