Im having problems with my van shutting off when the outside temperature rises past 60 degrees. It tends to start back up after 5-10 minute and continues to drive for about the next 5miles or so and then acts like it sucking air when u press the gas petal! i had the distributer replaced and the fuel filter, but not the feul pump. Please help save this vehicle from being salvaged. Thanks,Chris

i have a similar problem wit my 1998 safari van. it losespower and stalls when the temp reached 90%. 2 mechanics say it is the fuel pump. They say it was in the breakdown mode, explaining that it overheats and when it cools it works again, sounds like you need to replace your.
