Is it doing this on both the front and rear tanks? Was anything else serviced besides the two in-tank pumps?

First off, why were the pumps changed? What size motor, trans?

If both tanks are doing it then its probably not the pumps causing the problem... Have you tried pulling the codes yet?

I'd be looking at ignition issues. If there is an ignition component going bad, depending on your engine, after stalling, they seem to "fix themselves" after they cool off.

could that be even if the truck only stall once in a 40 mile drive then maybe 2 or three times on a shorter drive, its real spuratic.... got me scratching my head.

Pull your plugs and see if they're fowled. If not you might want to replace them anyways depending on age. Do a full tune-up and run some Seafoam through the gas tank and brake booster line. Should run like brand new ;)

Seafoam is a cleaner that can be used to clean many different parts of internal combustion engines.

It can usually be picked up at your local auto parts store.
