I sincerely would appreciate any help with this problem.

'87 Westy
90,000 miles (drive about 4k a year- not used much-mint)
Original owner (new problem -never happened)
Checked rotor,cap, wires and installed new fuel filter and 3 cans of gas
treatment (for water absorption).

Symptoms:
The van will hiccup or hesitate and lose power momentarily for maybe half
a second, like a hiccup. I watched the tach when it does it and it does
not go down to zero or fluctuate at all maybe when the hesitation is
about a second it may drop one indicator line on the gauge. The frequency
of this happening is now increasing- maybe once every 4 or 5 min.
When it happens: Uphill, cruising and downhill with foot on throttle.
Does not happen: Downhill with foot off throttle, 1st gear or at idle.
Possible areas- let me know what you people think:
fuel pump relay
fuel pump
ignition switch
distributor pick up (hall?)
air flow meter
ECU
I have the Bentley and a multi-tester, and fairly competent on many
repairs. I can also cook!!
Cheers, and TIA
